Good morning gents,
I have an odd question. Lately my 83 K20 will struggle to start. The starter sometimes sounds very strong and sometimes struggles to turn the engine or even engage. I went under it yesterday and saw that the wiring from the ignition switch was melted and the terminal for the main power feed from the battery was loose. Turning the nut on the terminal just spins it the whole terminal, it won’t tighten or loosen. I wrapped the melted wires with electrical tape and tightened everything down as best I could and the truck starts great, but I’m concerned about that terminal loosening over time. Is there a trick to removing the nut on the terminal without reminding the entire starter?

Replace the starter, repair and insulate wiring.

Once the terminals are corroded or burned only permanent fix is removal for buffing, sanding or replacement. Have to be clean or it creates heat which is what likely how the problem started.
