Electrical problems...I have no hair left.
Ok I have hit a wall here. 87 W250. I have currently reground it from battery to the body. I have a new battery, new alternator and my truck refuses to maintain power. I jump it and as soon as I pull the other vehicle off it drains and dies if i do anything electrical. All my problems started when I reground it and put a cd player in the truck. When i first put the alternator in I had to jump it. Had a small electrical fire and two wires burnt up. It looks like they were off the main fuse line. The thick 14 gauge red and the 18 gauge orange. When they were disconnected I had no ignition so i repaired them with wire nuts. I was able to start it then. I am going crazy here. Snow is coming and I want to play. What do I do? Please do not be afraid to insult my (lack of) intelligence on the matter.

Have you checked the voltage regulator? I would also run a separate ground for the regulator as that is a common problem with these trucks. The regulator does not ground well enough thru the screw to the fire wall alone.
I have 2 wiring diagrams that disagree with each other (I don't know which is correct) but on one of them the 14 gauge red wire that comes off the fuse panel feeds the ignition and is also connected to the voltage regulator. What are the colors of the wires on your regulator?
I also show an 18 gauge orange wire that feeds the radio.

Thanks guys, I removed the air filter and found it. I was looking for a small box that said "voltage regulator" on it per the picture in my haynes manual. I pulled it, cleaned the metal, then put it back. I ran a ground wire from the top left post to a bolt on the carb mount. Then I hooked my car up to the battery, let it run for twenty minutes or so and started it. Then let the truck run for twenty. Sounded strong, turned it off then it wouldn't start again, the solenoid just clicked at me. I think I will run to wal-mart for an ohmmeter to test it. Runs for 12 bucks. Is there a different way to test it? A new voltage regulator runs for 30 bucks. This is frustrating.
