Ugh…after uninstalling older electronics, my master power switch is not working

I don’t like the look of the bottom left positive red wire. Definitely closely inspect that. Looks like some strands have broken probably. I would also just gently tug on the rest one at a time to make sure everything is secure. If any movement repair/recrimp it or if you have broken strands from overcrimping or vibration through all those years of service.

Yeah, I agree and will replace that one and check the others.
