OK, I've got a big problem! My truck was running just fine earlier and I've never had any problems with it until today. My girlfriend was broke down so I went to help her, her battery was dead and we didn't have any jumper cables so I took the battery out of my truck and put it in hers to get it started. It started fine and I put the battery back in my truck. Went to start the truck and nothing! Not even a click from the starter. I had all my lites so it was working but wouldn't start. So we push started it and it started but when it did my dash lights and tail lights blew. The girlfriend followed me and after about a block I started smelling some serious electrical burning and my charge light came on. So I stopped and checked everything, it smelled like the started but I couldn't tell. So we drove it home (still running fine) with no tail lights or dash lights but the headlights and heater work fine. If anyone has any clue to where I can possibly start that would be a huge help! Thanks.
Yeah, I'd check the fuses, replace blown ones, that burnt smell is bad news if it was in the cabin... you're probably going to have to chase them down wire by wire like I had to do in my '88. The fact that everything was running fine before and then all went into chaos suggests that you probably knocked something while taking the battery out or putting it back in, maybe a ground or something. I'm assuming you put the battery back in with the correct polarity. This truck is not hard to take down to pieces, which is what I did. Took me a couple of days but it was worth it, all electrical gremlins are gone.
The truck is back up and running, replaced the 40 amp fuse under the Hood which got it started and replaced the tail light and blinker relays behind the kick panel and and everything worked accordingly for about 5 miles then the fuse blew and I lost the tail lights and blinkers. Replaced the fuse let set over night and the same thing happened again after about 5 miles. :/
Or the opposite, some ground came loose... happened to me when I was fixing mine; forgot to ground a couple of wires and I had to re-do a bunch of wires that I burned that way...
