Having problems with your 1986 GMC C3500 ?
My 1986 gmc diesel 6.5 litre has had a couple problems but the problem now is the truck is set up for manual glow plugs which were working fine but all of a sudden stopped and for some reason now my headlights dont work as well since glow plugs stopped. I checked fuses and they look find but i cannot figure out which fuse would be for headlights. I also tried plugging the truck in for a few hours and that does not work as well. Thought i would ask an experts advice thanks
