Hi Lawson,

 

As standard there are no fuses. There's a 30A thermal trip circuit breaker on the back of the lighting switch which will re-set itself. However, many owners install fuse panels so if they don't start working again by themselves I'm afraid you're going to have to hunt around :|

Looking at the wiring diagram it's on the feed side to the switch so yes, you should have lost all lights. Also, 30A would probably have welded your screwdriver to the light unit so I guess it's only hit that one circuit. Sounds like you need to play 'hunt the fusebox' :-(

 

(that or it's frazzled an already weak connection somewhere, but I'd look for fuses first.)

Hi mike i have sorted the lights out now and fitted a fuse board so next time i have a problem it should be easier to sort,,,,plus it makes me wonder how many gmc over the many years must have been burnt out due to a bad short out!!!! before the 30 amp would kick in there would be fire!!..Anyhow all sorted now thanks for your time and help...Lawson
