I've got another, minor, issue I'd like to pick the collective brain on. I have the mechanical issues on my '93 C2500 sorted out, so far. One problem it had when I bought it was the radio was bad but would occasionally power up. I know these trucks have a lot of trouble with grounds. I've replaced the radio with a nice Sony unit. It worked okay for several months then began to fade out while playing or not power up at all. I'm going to wiggle some wires the next time I can fool with it and may run another power wire from an accessory port.

I don't like Jack Legg engineering though. Does anybody know where the issue tends to be on vehicles like this? I used proper harnesses and no cutting and splicing of wires.
