zero power

[lbrewer]

South Dakota has been hit with a lot of snow lately. I was playing in the snow with my 1984 GMC K1500. I was driving through drifts and all of a sudden the pickup lost all power. I stopped and opened the hood, and the battery terminals were smokin' hot! I let everything cool down and never regained power. I did notice there was a wire harness that ran from the alternator to the starter? I think this is where it went, but it was snow packed, and some of the wires were broken off. I am unsure if there were broke, to begin with, or if they broke and caused the pickup to lose all power?

I am pretty sure I need to replace my battery. I'm looking for advice on the wiring scheme from the alternator to the starter. Or, how to best fix my power issue?

Not likely the battery at all. Sounds like you blew the fusible link in the 10ga wire on the firewall. Could have been with some help of some snow melting in the cowl and running down into the plastic/rubber wire channel. You can jump it or bypass it to get the truck running again, but I'd highly suggest to fix it right with either a slow blow circuit breaker, slow blow fuse or another fusible link. It's there for a reason. It blowing protected your electrical system and may have avoided a fire.

After the cool down we tried to jump it from the battery, just to make it home. Still could not get power. We did connect the positive cable directly to the starter and we got power. But, like you said I want to fix it right. We just pulled it home, ill run through the wires and check the firewall wire. Thanks

You'll see the fusbile link in that 10gu heavy wire. it looks like a black piece of vac hose about an inch or so long. You can test to make sure, by cutting it out and twisting the wire together. Once confirmed put something good in there in it's place.

Like a whole new wire with an in-line fuse that’s easily accessible.

Yep, either slow blow fuse or circuit breaker.
