I am hoping someone can help, I have an '83 series 3 109 24 volt FFR that has developed a issue with the lighting. On tail or tail and side it's fine but with head lights the n/s is fine but o/s no head light and the indicator is on rather than side light, in this state hazards flash opposite to each other, lights off they are ok, I have no full beam although the blue light is always on, the indecators do sort of work but I need the headlights on pull the stalk to flash position then I can indicate?? I assume it is an earth or one of the many relays but i am no auto electrician, I live in the bury st Edmunds area and any assistance would be greatly appreciated as I have no idea who to take it to...
