Gentlemen!
After much fiddling, cursing, and a mild electric shock or two, a friend and I have finally sorted out my headlight problem. (It was a broken cable between control unit and the plug, luckily near the front).
In our troubleshooting however, we found that someone at some point had reversed the wiring to the motor. We replaced the wires in this "incorrect" way, and it works fine.
This got us wondering if there are "LEFT" and "RIGHT" motors - or are they interchangeable?
If there are different kinds, how can one tell by inspecting the motor itself?
Because now I have a LOT of spare motors - and would like to know just what they are.
Cheers
James
