Car lost all electrical while driving

gtgto said

It was dusk out so I had my lights on for safety. My dash lights went out and my headlights, and the horn didn't work and my dome light also would not light. So vapor lock is out of the equation. I will get a chance later this week to check out the bulkhead connections.

Good. I mean not good but answers my questions.

I think it would be odd to lose both bulkhead feeds at once. Certainly check them out, but also remove and check all the wires you pulled on that night.

Even with the alternator out, the battery should have taken over unless something either grounded out or the ground connection was poor. Grounding out should not have killed everything so quietly. Check over the fusible link for sure, and anyplace in the line before the link that could have touched ground.
