Okay guys:
I talked with an automotive electrical rebuilder today and he said he knew that it was the voltage regulator, he's worked on a ton of them, some many years newer than mine. I don't feel too bad now, I knew that was about the only thing left. I took the truck to him today and tomorrow he's going to wire around the computer and install a regular voltage regulator and I'll get it back tomorrow. This SHOULD fix my problems.
Thansk to all who helped,
John
