After driving a 1600 cvh 4/4 for years I have just acquired a 1992 Plus 8.
Problem is that while driving around with the lights on,full beam, I was getting a little intermittent electrical buzzing from behind the dash. Side lights no problem. All was fine until I switched the engine off, leaving the lights on. (Poor practice I know.) I think I heard a little noise behind the dash as I did so. I then discovered the car is now electrically dead.
Help!
Any ideas ?
