Hi there,

I have a lhd 86 coupe, and it had the harness extended (before my time) to put the rear fog on the rh side of the car. The fog stopped working recently and on inspection the wires were oxidised, and as the extension was only joined by crimping, I decided to remove it and solder it properly.

I got the lh rear light unit removed and stripped back the fog cables to the originals ready to solder new extension cables. The original wires were also oxidised so I tried cleaning them in vinegar! I tested the voltage at the bare cables with the fogs turned on and I am getting around 11 volts - even with the engine running - is this enough to light a bulb? As I put a bulb onto the bare cables and it will not illuminate.

I unplugged the lh side harness in the engine compartment and there appeared to be some corrosion in there which I have tried to clean up. i then removed the harness earth which is bolted to the bumper shock - and broke the bolt in the process - how do I fix that?

So, I am at a loss, i have all but removed the lh side harness and still get 11 volts to the foglight, but still the bulb will not light - i have tried different bulbs. should i just look for a replacement harness? With the wires oxidised are they no longer any use?

Cheers
