    Hello all,
    New to the site and I just picked up an 86 k20 from a guy who was gonna scrap it. He said it ran fine and one day just died while driving. I’m not a mechanic I’m a parts changer so I can turn a wrench but I don’t have ton of knowledge. I checked the fuses and the ground to the alternator. All good The headlights work but nothing else. When you turn the key on No radio. No turn signals Nothing. He did say the wiper stopped working shortly before it died. Anyone got any ideas.

    probably a burned out fusible link near the starter. The main battery power goes to the starter and then has two fusible links that come off the starter and run to the fuse blocks. I would get a multimeter and start testing for continuity until I found the blown link. Then check to see if you have a short to ground before you try and replace it.

    I have heard mention of engine compartment heat doing a number on the fuse block connector that runs through the firewall.
    That's something I need to check out on my 83 with power loss issues.
    Best of luck figuring it out, and welcome to the forum !!

    I checked my 83 C20 fusible links, and I have power all the way to the firewall connector, but most circuits on the other side are dead, I am going to pin the blame on the fuseblock under the dash ...........
