My uncle bought a 1965 C20 last week. The truck had been driven somewhat frequently, and he has been driving it around.

Well, the other day all the rear lights went out. He has checked the fuses and they're all fine and hasn't seen any bad wires right off.

So, any ideas how he should start tracking down the problem? What to look for? I'm no good at the electric system!!

Off topic - but he got a great truck for $700! It's SOLID and has a wonderful engine! For anyone interested, there are photos in my blog...
