This 306 came with a list of electrical problems, no big deal or so I thought.
The high priority job was enable the engine to stop on the key.
This is a safety critical repair, the first task was to get the engine started, the battery was completely discharged. A sure sign of the trouble ahead.
Once the engine started with a booster pack, you could remove the key and the thing kept running until you switched the lights on then off!
I fitted a replacement battery after cleaning all traces of electrolyte from the battery tray and surrounding areas. This restored the key to normal operation, but the side lights refused to switch off, plus the brake lights were on permanently.
The culprit, the brake switch had become dislodged. With the switch re-fitted and correctly adjusted we now had working brake lights, however the side lights came on every time the brakes were applied. I was beginning to think this was some sort of joke, but this is normally a simple case of incorrect filament lamps being fitted. Sure enough one of the brake light lamps was a single filament instead of a double filament, this back feeds the side light circuit putting the side lights on whenever the brake pedal is pressed.
The list of jobs was slowly reducing, but now I had to sort the passenger electric window. More on this next time.
