Chapter 83 Week Fifty-Three December 17, 2007

This week begins my second year of restoration assembly. I have some time off in the next two weeks so I am hopeful that at the end of the Christmas holiday I will have my front body components on the car.

While waiting for the carb repair, I decided to start a little work on the hardtop assembly. Most of my hardtop restoration components came from Bill Bolton. The hardtop fabric he supplies is very close to the original. I has previously refurbished the headliner frame and had it along with the front cushion covered by Gerry Smith at Classic Upholstery. I glued the fabric to the lower hardtop aluminum cant rail.

Fabric was also glued into the corners of the hardtop where the front mounting “J” hooks are located.

Then I glued some carpet padding onto the hardtop to provide cushion for the headliner frame rails.

My repaired front carb returned from Joe Curto yesterday (December 18). Joe replaced the diaphragm. I installed the carbs last night and pleasantly, no leaks! Now I will leave the hardtop work and return to installing the body.

Front SU carb re-installed

I covered all of the edges of the scuttle that come in contact with the front shroud(bonnet surround) with 3M strip caulk. This will prevent heat, fumes and water from entering the cockpit. To make sure I had adequate build up of the caulk, I used a tip from Jack Brashear. I covered the strip caulk on the scuttle with wax paper, installed the shroud and then pulled it off. Where the strip caulk was not pressed against the the wax paper I added more caulk and repeated the process until I was satisfied that I had enough caulk in place.

Ready for the shroud 2

Securing the front shroud to the superstructure was the next step. I began by installing 3/16” aluminum pop rivets in the rear of the shroud along the dashboard flange (5) and scuttle edges(2 per side).

Shroud rivets

I then installed five countersunk flat head screws through the rear flange of the bonnet opening into the edge of the firewall.

Four bolts, washers, and nuts fasten the frame rails to the shroud at the front of the car. The frame rails should fit “inside” the shroud. Three #10 flat head, countersunk machine screws with washers and nuts fasten the front flange of the bonnet opening to the superstructure.

Two #10 flat head, countersunk machine screws with washers and nuts fasten each of the vertical shroud support brackets to the shroud. On the RH passenger side of the car, one of these screws, along with another, is also used to fasten the bonnet prop rod stay bracket.

The front shroud was now fastened in place! I then attached the carb access panel and I was in business. The panel measurements are in the image below.

I had a surprise visit from my 9 year old grandson, Tyler. As the photo shows he is getting ready to drive the “Bloody Beast.”

Tyler ready to drive

The two windscreen washer jets were installed on the shroud (would have been much easier to do before the shroud was put in place!) and connected with rubber tubing to the reservoir in the parcel shelf. I had previously installed the wiper motor, crosshead and rack, but I now needed to bring the wheelbox assembly up through the front shroud and secure them in place with the rubber washer, chrome bezel and chrome nut. This was not a pleasant job with all the wiring and underdash components in place, but after some struggling the job was accomplished.

Chapter 41 Restoration Assembly, Week Eight 2/5/2007

With the steering behind me, I thought it was time to install more of my electrical accessory items. Most of the bits fasten behind the dash in one form or fashion, so I wanted to get them all located, mounted and wired before the dash fascia was installed.

Intermittent wiper control – The big Healey came standard with a one speed (slow) windscreen wiper motor. Ed Esslinger, a member of the Tiger United Club designed and built a wiper control unit to provide intermittent wiping of the windscreen and made them available for sale. edstiger@charter.net  334-774-5155. I purchased the kit to install in the Bloody Beast. Ed’s directions were detailed and easily followed. wiper control directions.pdf

Ed provided for a mechanism to connect the wiper control with the lights so that the lights are on when the wipers are working – now a requirement in many states. The wiring from the relay (shown to the right) connects to the control unit, ground, and to the lighting switch. Including an optional rectifier diode between the S1 and S2 terminals on the switch provides for operational parking and tailights while the wipers are working as well.

Intermittent wiper bracket

I used a double wiring connector to join the two brown/blue wires that originally linked to the A terminal on the switch with the brown wire from the relay, and then ran one brown wire to the A terminal on the light switch.

I had Martin Jansen install headlight buckets in the holes in the scuttle side panel assembly to use for mounting speakers, but decided against using them for that purpose, but they make a nice “hiding place,” so I decided to use the one on the left side of the car to “hide” the control unit for the intermittent wiper control module. I made a little bracket to secure it and then mounted the assembly with two stainless self tapping screws into the bottom of the headlight bucket.

The wiper motor installed fairly easily. It mounts on three posts with rubber buffers. I temporarily tied the rod to the scuttle with plastic ties.

Next came the dash fascia. I mounted it with the four #10 machine screws on the outside edges and one through the dash in the middle. I held off on the two support braces until after I finish all electrical and heater work behind the dash.

Removed the three mounting bolts in the bottom of the wiper motor. Disconnected the three wires from the junction. Removed the lateral brace from the steering wheel column to the left body wall (two bolts). The three wires are green, green and black, and black and connect through the grommet hole below the choke hole in the firewall to the primary wiring harness. The two large chrome nuts are removed from the wiper box shafts and the shafts can be withdrawn under the dash. The motor and wiper boxes can be removed along with the connecting cable by sliding it above the steering wheel toward the passenger seat.

Power Inputs to the Classic Technologies’ Relay/Fuse Panel

The Classic Technologies Panel has four primary connections.

Classic Technology's Relay Fuse Panel

Classic Technologies’ Relay Fuse Panel

A – 12V power input from the small fuse box (battery B+) to power the accessories circuits. A brown 12 AWG wire is used to the Yellow screw terminal spade lug connection.

B – 12V power input from the small fuse box (battery B+) to power the high and low beam headlight relays. A brown/blue 14 AWG wire is used to the Blue screw terminal spade lug connection.

C – 12V power input from the small fuse box (battery B+) to power the constant power circuits in the vehicle. A brown 12 AWG wire is used to the Red screw terminal for a spade lug termination.

O – ground or earth to the car’s chassis.

In my case, 12V power is routed from the battery in the trunk to the starter solenoid mounted centrally on the firewall in the engine bay. The negative terminal of the battery is wired to the car’s chassis. A ground strap is used to connect the grounded chassis to the engine/gearbox.

Ground Strap Mounted

The battery relocation to the boot was addressed in a previous post.From the solenoid, a brown 8 AWG wire delivers power to a small fuse box with six circuits mounted on the firewall directly below the starter solenoid. I used two nutserts for the mounting to the firewall.  Three of the six fused circuits are then used to provide power to three input terminals on the Classic Technologies’ relay/fuse panel. The additional three are spares for the moment.

The three wires from the small firewall fuse box, the white/red wire from the solenoid to the fuse panel and the heavy 4 AWG cable from the solenoid to the alternator will be “packaged” together in one TechFlex sleeve/cover.

Before getting into the allocation of the thirty-four fuse positions available to use in the Classic Technologies Relay/Fuse panel, it might be helpful to once again point point out that as indicated in the post on new wiring harness connectors I developed a spreadsheet to be used in conjunction with wiring diagrams. The spreadsheet lists all connection points of the electrical wiring system. Links are provided below:

Again, a disclaimer is appropriate: The spreadsheet is provided as guidance for those who might wish to do something similar, but it should not be duplicated or utilized without careful inspection and  approval by a certified automotive electrician.

This alphabetical listing of components is provided to help quickly identify items in the electrical system. A spreadsheet line number(s) associated with the component is indicated.

Circuit Modifications & Additions

Several of the modifications I am making to my MK2 require either modified or new electrical circuits. I highlight below the details of some of these wiring changes.

Starter Solenoid

I replaced the original starter solenoid with a new one sourced from SNG Barratt. The large post closest to the firewall provides the mounting for the 4 AWG cable to the starter. The large post closest to the engine mounts three cables: the 2AWG cable from the battery, the 4AWG cable to the block connector on the electrical panel on the LH engine bay valance (ultimately to the alternator), and a 8AWG wire to the 6-way firewall fuse panel. On the upper small post on the solenoid a single wire from the starter button is attached.

Alternator

I have considerably more power requirements in my car than could be addressed by the original dynamo/generator.

The specifics of the Hitachi 120 amp alternator I am using may be found under the “electrical components” posting. However, I will detail the wiring to support the alternator here.

I decided to go with 4AWG cable and also decided to install a fuse in the line between the alternator and the wiring system to avoid any possibility of a problem with a power surge created by a bad regulator in the alternator.

I sourced the cable and fuse from CE Auto Electric Supply. The folks at CE Auto Electric Supply are very helpful and they sell high quality products. Both products are typically used in high-end sound system applications. This particular cable has 1,862 strands. The cable was terminated with 3/8″ terminals, properly crimped and covered with adhesive shrink tubing.

Alternator Cable CE Supply 4AWG 1862 Strands

Alternator Cable CE Supply 4AWG 1862 Strands

I installed a JL audio premium series master ANL fuse block with a 125 amp “Stinger” ANL style fuse, part number SPF52125 on the lower right portion of the original fuse panel.

ANL 125 Amp Fuse with J&L Holder

ANL 125 Amp Fuse with J&L Holder

Two three-quarter inch long machine screws were used to secure the fuse block to the panel. On one I was able to take advantage of the 10–32 captured nut that was already on the fuse panel, and on the other I used a nutsert with the 10-24 screw.

One of the nice features of this particular fuse block is that the ProStar hexagonal posts can be rotated so that the cable can approach from almost any angle. As you can see in the photo, I took advantage of this feature. After the engine is installed, the alternator cable will be cut to proper length.

As can be seen in the image, the cable from the ANL fuse connects to a connector block also used for the power steering.

Alternator Fuse Mounted

The cable is then routed from the connector block along the LH valance and the firewall to the starter solenoid. It is difficult to track because of all of the in-process wiring, but the path of the alternator cable is visible in the image below:

Alternator Cable Wiring

Power Steering Pump

The installation of the power-assisted rack and pinion steering requires the conversion to negative earth and the installation of an alternator replacing the original dynamo/generator. The kit, as supplied, provided a Lucas 80 amp LMA 604 alternator. However, due to other electrical requirements I chose to upgrade to a 120 amp Hitachi alternator. Details about the alternator are found at this link: https://valvechatter.com/?p=4113.

M&C Wilkinson provided wiring instructions, but my configuration is slightly different than in the application they referenced. The wiring diagram below is my interpretation of the wiring required for the pump in my car.

Five wires emanate from the pump. The heavy brown wire connects to ground. The heavy red cable connects to the supplied 80 amp fuse. The 22 gauge black wire connects to the fuse panel at location #19 or #23. The 22 gauge blue/slate wire connects to the alternator at the indicator lamp post.

Heater Fan Wiring

A full description of the restoration and modification of the heater box and fan may be found at the Heater Post on this Valvechatter website. The following information addresses the wiring of the heater fan.

The orange wire from the motor is connected to ground. The black wire to the “inside” post (closest to the heater box) of the resistor. The slate wire from terminal #6 on the switch is connected to the “outside” post (closest to the blower fan) of the resistor. The white/green wire from terminal #8 on the switch connects to the “inside” post on the resistor. The green/yellow wire from the #4 terminal of the switch is connected to the fuse position #11 for power. With this wiring in place, the lower position of the switch is “off,” the middle position is “Low Speed” and the upper position is “High Speed.”

I created a pigtail (seen below) from the resistor for the heater fan wiring. Two wires in the pigtail are connected through two-way snap connectors to wires of the same color which route through the firewall and ultimately back to the Fan Switch. The black wire in the pigtail goes directly to the fan motor. The orange wire from the motor is the ground and it is connected to the LH valance grounding terminal strip.

Wiper Motor Wiring

As documented in my post entitled Wiper System Upgrade, I installed a Lucas 29W wiper motor kit from Classic Motor Cars in the UK. The upgrade includes a relay mounted behind the central instrument panel assembly. The wiring for the wiper switch is referenced above under the section “Instrument Panel Assembly Switch Wiring.” This is a diagram of the wiring:

A full description of the installation of the Rostra Cruise Control System in my MK2 is provided in the MK2 Cruise Control Post. My wiring diagram, tailored for my 1964 Jaguar MK2 application, is provided below. As the disclaimer above indicates, the wiring description in this post journals what I did for my car. It is not my intention to describe what you should do for your car!

This is a link to a pdf of the wiring diagram and it is also shown in the image below:

Central Locking and Keyless Entry Wiring

A full description of the locking system may be found at the “Remote Control Door Locks web site entry: https://valvechatter.com/?p=9205. The wiring for the system is comprised of two components. The MES Central Locking Control Module operates the door lock actuators. Once that system in properly installed and operating as it should, the AVITAL keyless entry module is added to permit use of a key fob to wirelessly lock and unlock all doors. An added feature of the system is that about fifteen seconds after ignition all doors are locked automatically. 

The following wiring diagram is unfortunately a bit busy. This is a link to a pdf file of the diagram: Keyless Entry Power Locks for Rose Jag MK2 and a jpeg file is depicted below:

Air Conditioner Operating Controls Wiring

A full description of the installation of the RetroAir air conditioning system in my MK2 is provided in the “Air Conditioning” Post. The wiring of the controls and devices for the air conditioning system is depicted in the following diagram:

Rose Jaguar MK2 Air Conditioning Wiring

Rose Jaguar MK2 Air Conditioning Wiring

This is a photograph of the wiring harness provided in the RetroAir kit. In my application I did not use the circuit breaker shown in the image because I wired the blower switch directly to the fuse panel and protected the system at that point with a 40 amp fuse.

RetroAir Wiring Harness Kit

As the diagram above illustrates, I chose to install a trinary pressure safety switch in the air conditioning electrical circuit. The trinity switch is also discussed in the “Air Conditioning Post.”

Vintage Air Trinary Switch

Vintage Air Trinary Switch

The Vintage Air trinary switch kits combine low and high pressure compressor clutch cut-off functions plus an electric fan engagement signal at 254 psi. The low pressure cut-off of these trinary switches is 30 psi and the high pressure cut-off is 406 psi.

http://www.vintageair.com/Instructions2013/904678.pdf

The switch as supplied has two blue wires and two black wires. Because the switch is located in a right from wheel well and exposed to the elements, I connected the four wires to a waterproof connector purchased from British Wiring, and then routed the wires to their termination points. One blue wire is for ground and the other for fused power. One black wire connects to the compressor and the other to the thermostat controller for the air conditioner.

Turn Indicator and Headlamp Flasher Switch at the Steering Column  and the Laycock De Normanville Overdrive Switch and Wiring

The electric overdrive is activated by a lever switch on the right side of the steering column. Power is derived from fuse position #14 of the CT fuse box. With lever activation a signal is sent to the overdrive interlock, or top gear switch located on the top of the gearbox and then to the overdrive solenoid. A warning indicator bulb is illuminated when the overdrive is engaged. More information about the switch and lever mechanism may be found in the “electrical components” post.

Overdrive Interlock or Top Gear Switch at gearbox

Overdrive Interlock or Top Gear Switch at gearbox

The lever on the left side of the steering column is used in an upward and downward motion to activate the LH and RH turn indicator flashers at the front and rear of the vehicle. When the flashers are functioning an indicator bulb located in a centralized position behind the steering wheel is illuminated in a flashing pattern. The headlamp flasher is activated by the driver pulling the same lever toward himself. This action will trigger the high beam warning light in the speedometer.

Although the wiring harnesses were complete, there were a number of electrical connectors on the harnesses with no explanation as to what needed to be connected where to get the seats functioning.

Seat Wiring Harness and Switches

Seat Wiring Harness and Switches

The seats have seat heaters (upper and lower cushions), a memory feature for the driver’s seat, seat belt alarms, and wiring to permit automatic movement of the driver’s seat to the aft position when the driver’s door is opened.

After some enquiries on the Forums, Bryan Neish came to my aid. He was of great help figuring out what the wiring at each of the connectors did. I know he spent quite a lot of time reviewing wiring diagrams to find what I needed. George Leicht was also helpful. He sent along the wiring diagram that accurately reflected my seat wiring.

I wired the seats to unswitched power at the fuse box to facilitate seat operation before entry or before starting the ignition. I was able to use the original seat wiring harness and bank of switches to control the four motors adjusting the lower and upper seat cushions for each chair. The wiring runs under the center console to each seat. A pdf file of the seat wiring schematic for 1990 may be found here: 1990 Jaguar XJ40 Seat Electrical Schematic

I have yet to decide where I will mount the switches. The image below shows the approximate location of the switches as Ton Tulleken installed them on his car:

SideLights

Additional detail about the sidelamps may be seen in the exterior lighting post. I rewired the original side lamp fixtures and trial fitted them to the body. The rubber “O” rings supplied by SNG Barratt are to thick to fit properly so I replaced them with metric 24mm – 2mm “O”rings ordered from McMaster Carr. New LED bulbs were also fitted in the fixtures. The red 18 AWG wire from the bulb is combined with a black 14 AWG ground wire from the fixture in a vinyl sleeve that goes through the LH and RH valance lighting grommet.

After installing the side lamps I moved to the turn signal flashers. Information about the lamps is contained in the exterior lights post. I re-used the original fixture wire terminals but replaced the power and ground wiring with new. The power wire is blue/green 18 AWG and the ground wire is black 14AWG. The wiring is pushed through holes on the back end of the fixture’s new rubber boot. New vinyl sleeving was also used for the flasher lamps.

Fograngers

More information about the fog rangers may be found in the exterior lights post. The Classic Technologies Fuse box did not have a relay designed into the product for fog or driving lights, so I added a Bosch relay for this function. It is mounted on the original fuse panel in the engine bay on the LH valance. The foglights are controlled by the primary light switch.

Tail Lights

More information about the tail lights may be found in the exterior lights post. I substituted LED bulbs for the original incandescent type; however, the wiring remains the same. In fact, I was able to reuse the original wire leads from each of the bulb holders. The upper bulb is for the flasher with a single wire lead. The lower bulb is for the regular lights plus an additional light for the brakes with a double wire lead.

More information about the lamp may be found in the exterior lights post. The lamp includes one light for the luggage compartment, two bulbs for the license plate illumination, and one bulb for reversing. All original incandescent bulbs were replaced with LEDs. The original wiring harness for the lamp was in pretty good shape, but I constructed a new one with all fresh wiring.

Boot Lamp with new wiring harness

Luggage compartment lamp

As my friend Eric Kriss points out in his MK2 restoration blog, the luggage lamp seemed to be an afterthought to Jaguar engineers. To function the light switch on the gauge panel had to be turned on, but it is often the case that one would want to access the luggage area after the car’s ignition, much less its lights were turned off! Instead of wiring the luggage compartment lamp in series with the front marker and rear tail lights, Eric revised the wiring to move the luggage compartment lamp to its own circuit. To make the lamp illuminate when the boot lid is opened a position sensitive mercury tilt switch is used. As Eric describes, when upright a ground connection is established permitting current to flow to the bulb. When the boot lid is shut, the ground connection is broken so the light goes off.Mercury Tilt Switch

 

Interior Lights

The MK2 as original had six interior lamps: the map light at the central gauge panel, a lamp at the top of each center or “B/C” pillar, a lamp in the cubby box and a lamp on each side of the rear of the car above the passenger seat. These latter lamps referred to as rear quarter interior lamps. My Mk2 will also have two courtesy lamps in the back of the front seat headrests. More information concerning these lamps may be found at the “Interior Lights” post.

As pointed out in the “Interior Lights” post, the replacement center pillar lamps are not exact replacements for the originals. They are operationally superior in that they provide an “on-off” switch at the lamp, and also because they screw, rather than snap, together. They just don’t look quite as nice being plastic rather than chrome metal. Just to check fit and to test the electrical system I did install the new center pillar lamps mounted on their wood bases. An additional grounding wire is used with the new lamp for its switch so there are three wires rather than the original two. For purposes of testing the electric system I temporarily fixed the third ground wire to the pillar as shown in the third photo below.

36 mm festoon bulbs in warm white were substituted for the original incandescent bulbs.The lamps are wired to the interior lighting circuit that includes the interior lamps toggle switch on the central gauge panel as well as the four door switches. The black ground wire is simply attached to the metal center pillar.

I trial fit the new, but as original, rear quarter lamps which required making new plywood mounting frames. Wiring for the rear quarter interior lamps initiates at fuse box to the interior lamp switch on the gauge panel and then proceeds through the LH and RH sills to the lamps. There is also a switch in each door that activates the interior lamps should any of the four doors be opened. I did not use wiring pigtails for these lamps. 36 mm festoon bulbs in warm white were substituted for the original incandescent bulbs.

I am using XJ40 powered seats in my MK2. The seat headrest lights were originally wired in such a way that they too illuminated when the car’s doors were opened. These lights also have an integral on/off rotary or dial switch. Without the central processor of a more modern car it would be all too easy to leave these lights on and eventually drain the battery. Therefore, I elected to wire these lamps to a switched power source rather than a constant power source like the other lamps. I did not use the terminal on the headrest light that would normally have a red/green wire to the door switches.

I was able to use the original door switches in my rebuild. I just rewired each of them with new wire.

The Cubby Box lamp assembly wiring for Lamp/Switch consists of a metal base fixture, bulb, blue plastic cover and a switch controlled by opening the Cubby Box door. More images and information regarding the lamp may be found at the “Interior Lights” post. As with the other interior lamps, the original incandescent bulb was replaced with a 36 mm festoon bulb in warm white. Terminals on the back side of the metal lamp base connect to the fused power source and to the Cubby Box door switch. The image below illustrates the wiring sources and terminations for the Cubby Box.

Some Details on a Few Other Assemblies

The LH and RH Fascia Board Assemblies were installed in the car so as to test the wiring for the speedometer and its warning lights, the tachometer with the internal clock, the “Handbrake “ON” position and brake fluid container level” warning lamp, and the “Cubby” glove box lamp. More information on these fascia boards may be found at the “Dash” post. All gauge/instrument illumination incandescent bulbs were replaced with LEDs.

I first connected the left turn signal flashing indicator, the right turn signal flashing indicator, and the overdrive engagement indicator from the indicators wiring pigtail to the direction indicator/headlamp flasher switch. A ground wire for the indicators was mounted to the body below the dash.

I found it easiest to loosely position the driver’s side fascia board and I then installed the tachometer with its two mounting clamps, a ground wire, the 12 volt power wire, the wire connecting the tach to the coil and the two instrument lights. Leaving the speedometer position open facilitates accessing the LH fascia board outside mounting studs/nuts.

I then secured the LH fascia board to its mounts, followed by connecting the wiring for the handbrake/brake fluid level warning lamp.

I then connected the two speedometer illumination lights, the lights for the headlamp, ignition, and fuel warning lights, and the speedometer drive cable.

Installing the passenger side (RH) fascia board is much the same as the driver’s (LH) side. A sliding panel in the cubby box may be removed to provide access to the studs/nuts of the outside mounting bracket. The wiring for the “Cubby” lamp as shown in the write-up and image above is connected to ground and power.

Fuel Sender

The fuel sender has its own short wiring harness consisting of three wires in a protective sleeving. One wire for ground, one for the fuel gauge (the “T” terminal on the sender for 10 volts) and one for the fuel level warning lamp in the speedometer (the “W” terminal on the sender). The embossed terminal markings are evident on the image below. My sender has an “E” marking for earth, although my grounding wire was fixed to one of the screws used to mount the sender to the tank. While the original harness was in good shape, I made a new one for installation in the Jag when the fuel tank is fitted.

Warning Light for Handbrake and Fluid Level

The lamp is activated by a switch at the base of the handbrake, mounted to a bracket located on the interior floor. See: https://valvechatter.com/?p=3913 under the handbrake post, or by a level indicator switch in the brake fluid reservoir is shown earlier in this post.

Handbrake Warning Switch

Handbrake Warning Switch

The “Warning Lamp Indicating Handbrake ‘ON’ Position and Level in Brake Fluid Container” is comprised of the cover and window assembly, a spring washer on the central terminal post, with nuts and washers. Rubber sleeves are slipped over the white wire at the terminal and the white and red/green wires are contained together in a rubber sleeve of about 4.” The warning light was cleaned and reassembled and a new face plate was installed.

Two wires attach the switch with spade connectors and are protected by a rubber cap over the indicator plunger. I sourced a new canister and indicator switch (cap) from SNG Barratt. The canister is covered in blue painter’s tape just to keep it clean during the restoration build. I was able to reuse the original rubber protective cap. An 18AWG light green wire is connected to one terminal. This wire joins via a 4 way snap connector with an orange 18 AWG wire from the handbrake switch. A single orange 18 AWG wire then connects to the LH Barrier Block Terminal #5B. A dark green wire from LH Barrier Block #5A connects to a 2 way snap connector with a red/green wire on the dash warning light pigtail.

A black 14 AWG wire connects to the other level indicator switch terminal and provides a ground connection to the chassis.

Wiper System Upgrade

Wiper System Upgrade

I am upgrading the wiper system with a kit provided by Classic Motor Cars. http://www.classic-motor-cars.co.uk/servicing_types/mk2-lorem/.

The kit uses a model 29 W Lucas Motor, part# 75967D that I believe was used for XJ series Jags in the eighties and early nineties with a modified original switch to operate the system.

Installation

I had already removed all of the original wiper system from the car. I installed the RH Bonnet Hinge and the Fuel Filter and Fuel Pipe to make sure that the mounting of the wiper motor would not foul or interfere with these components.

1. The first step was to install the new wheel boxes. These are a slightly different shape than the originals but held by new chrome nuts supplied in the kit they went right into place.

2. I attached the wiper motor to the kit-provided mounting bracket using the hoop clamp and the rubber cushion to address vibration. The bolts were also provided with the kit.

3. The original rack tube is used between the two wheel boxes. This is a straight piece that drops in once the covers for the wheel boxes are loosened.

4. A new rack tube end piece (about 3″ long) is provided in the kit and is shown in the last of the previous images. It is open at the end to permit the rack to slide through. The provided rack is longer than it needs to be to allow for flexibility in mounting I assume? The open-ended tube allows one to determine how much of the rack is to be removed.

5. Using the original curved rack tube that extends through the firewall as a guide, the new tube provided in the kit is bent to conform to the same shape.

6. I then tested my bending skills by inserting the tube through the firewall and connecting the one end to the wheel box and the other to the motor while holding the motor on its bracket roughly in place on the RH valance in the engine compartment. Once satisfied with the fit, I marked the location for the two hex head bolts that mount the motor bracket to the valance. I then disconnected the tube at both ends and withdrew the motor and tube from the car.

7. I drilled two 3/8″ holes in the RH engine bay valance to secure the motor bracket.

8. The rack was then fit to the motor. This required taking the cover off the motor and inserting the rack end fitting to the peg on the action lever in the motor. I then buttoned up the cover and slid the curved rack tube over the rack and tightened it to the motor.

9. I then fed the rack through the RH wheel box, the center straight tube, and then the LH wheel box. This required an additional helpful person to hold the wiper motor in the engine bay while I fed the rack through the boxes.

10. I then bolted the motor bracket to the valance using two hex head 5/16″ – 24 x 3/4″ bolts, with flat and shake-proof washers. The kit provided 1/4″ bolts, but I substituted the 5/16.”

11. The rack was approximately 6″ longer than it needed to be, so I trimmed it to proper length with a dremel tool.

12. The kit provides a relay, a modified switch and some wiring. To make sure everything was functional I connected all terminals between the motor, the relay and the switch, secured the ground connections and attached it all to a power input. Everything worked properly.

13. After the car is painted and before final installation, I will grease the rack for smoother operation and add a grommet to the firewall for the rack tube and one for the wiper motor wiring. I plan to use:

Molykote® Bearing Grease Designed for Extreme Low Temperature ApplicationsMIDLAND, Mich. – August 12, 2005 – With a service temperature range of -100° to 400°F (-73° to 204°C), Molykote® 33 Extreme Low Temperature Bearing Grease is effective at lubricating plastic gears, bearings and cams, as well as metal and rubber parts that must remain operable when subjected to low operating temperatures, severe weathering and oxidation.

Molykote 33 Extreme Low Temperature Bearing Grease can be used on freezer cart casters and cold room conveyor equipment; utility disconnect switch contacts; plastic electric clock motors; maximum-demand meters, power-factor meters, watt-hour meters; windshield wiper motor gears; photographic, optical

The three images below show the mounted wiper motor and the rack tube through the firewall.

A Little Wiper Work

Wiper WorkPlanning on attending The British Car Fest in Buckeystown, MD on Sunday the 27th, so we needed to get a few maintenance items taken car of on the Bugeye. We had never reinstalled the wiper motor when we finished restoring the car so that was the first job. We pulled the dash off the car which may not have been required but it did make access much easier. After much trial and error with fitting it was figured out and the motor and wipers were installed and made functional. The sweep doesn’t seem to be sufficiently wide so a little more research is needed to determine how to adjust.

The brake lights were not working. I connected the two brake switch terminals with a wire and the rear lights functioned, so I determined that the switch was faulty. I put a little brake fluid in the new switch, quickly removed the old one and reinserted the new one. Voila! Brake lights returned.
