Wiper motor wiring

[tigernewbie]

I had originally posted a message asking for help in wiring my wiper motor back up. I decided to edit my original posting because it had become no longer valid. In case this might be helpful to anyone, I have just figured out on my own car that the green cloth wire from the wiper motor goes to the double green wires from the wiring harness, the red cloth wire from the motor goes to the red/light green wire from the harness, and the brown wire goes to the brown/light green wire. I had accidentally disconnected all three wires from the wiper motor and was mystified that there were five wires from the wiring harness to choose from. Cheers.

If you have the 2 speed. the green with the bullit connection goes to +ve green. The other 2 spade terminals go to the switch that also has an earth connection to it. Therfore earth is switched to either of the leads to provide high & low speed. There also aslo a black lead with a ring attached that goes to earth. If all correct, it works, if not a rebuild is needed, a bit of a bugger to get at and refurbish. There is also the brown lead from the motor that connects to the parking circuit under the cover. If thats grunged up, it needs a clean at least.

Thanks. All began working properly when I figured it out earlier. Since when I adopted my car it was essentially a barn find, almost nothing had been rewired since it left the factory. The wires to and from the switch were as they were back in 1966, complete with their unreliable Lucas connectors. I just did not know which wires from the motor went to which wires from the switch because, while they were similar, there were no complete matches. In other words, the solid green from the motor did not go to a solid green wire from the switch, but a green an red.

One other thing I learned and should mention is that after about a week, my motor stopped working again while driving over a rough road. Disheartened, I went and bought a remanufactured motor from XKs Unlimited (they ended up with a motor in their stock in the mid 90s and had no use for it. (I used to have an XKE, so I am a previous customer of theirs). Then, before I could do any new work to the car, I inadvertently touched my knee near the steering column and the original motor started working again. I moved my knee and it stopped working again. After a little fiddling, I understood that there is a common ground wire that connects to a bracket under the dash in that area that was loose. I tightened it and all is wonderful again with the original motor.

Lesson learned: Before going out and spending money on electrical parts, do yourself a favor and check all the ground connections you can find, even if seemingly unrelated to an electrical part that seems to be having problems. As for me, I now have yet another spare Tiger part in my collection, which has grown to absurd proportions over the last years. Ugh.
