Re: update on 1979 K10. Everything dead but the lights

The wiring deviation that replaced the J-Studs is loose and or corroded. This is your gremlin. It will be back.
Loose connections can cause an electrical fire and they do heat up the wire making it brittle.
Trying to charge the battery through a corroded or loose connection certainly will not help the alternator to live a long prosperous life.
It'll be cheaper to repair it before it burns out the alternator and much easier to repair it before you have an electrical fire.

Cheers.
