I just bought my first kombi, 1978 Bay window 2l. All the lights work except the rear number plate light and right rear brake light and driving light. I have tried the globe on the left side light fitting and the globe is working. I have also done a continuity test and seems ok although the light on my tester didn't shine up as bright when I tested the right rear brake light fitting. The second fuse from the right hand side of the fuse box blows as soon as I fit a new fuse even when ignition is off but i'm not sure that this is affecting the brake light and any help with why this would keep blowing would be very helpful. Could somebody take a photo of the inside of the rear right light fitting so I can check that mine is wired up correctly? I also was reading about wires being loose on the brake booster causing a problem. I had a look under the front where the brake pedal comes through the floor and found what looks like a brown earth wire not connected to anything. Wondering if somebody knows where this wire should connect up to and if it has anything to do with my brake light not working?
