Spiking voltmeter, then no start, intermittent cabin power

Hey folks, I hope y'all are beating the heat - not much chance for that around here. I typically like to do more thorough research before asking for help, but I've got a decent excuse: I promised the church I'd use my truck to help out with a community service project tomorrow morning, and I can't get it started. The last time I drove it, the voltmeter was spiking kept climbing as I drove - I had to hit the window buttons to drain off some of the voltage to keep it from climbing too high. When I got home, something or other drove it from my mind.

Next morning, I couldn't get it to start - no Wait to Start, no cabin lights, nothing. I checked the main fuses and they all looked good. I walked around to the passenger side to get put the owner's manual with the fuse list back in the glovebox and the dome light was on. Walked back to the driver's side and had nothing - no lights, no Wait to Start, no crank. Reached across and opened the passenger door, no dome light this time. I checked the batteries and they showed 12.6 or so, although I didn't bother to disconnect them from each other first.

Recently I've changed out my GPR for a new Stancor, put in a reman alternator, and (about six months ago) got new batteries. I also put new terminals on the lines coming into the passenger side battery.

I'm going to go and fiddle with it, but I'd welcome any quick suggestions so I can go help out those folks tomorrow and not have to back out on my promise!

Thanks to everyone, as always.

So after poking around further I saw that the cable going down to the starter had slipped out of the clamp holding it and the crossover cable to the terminal end. I retightened the whole thing and got a good crank and solid start. I'm hoping that was it, but I'll find out more in the morning when it's time to go.

Sucks that I had to embarrass myself with such a boneheaded mistake in a public forum, but at least it was an easy fix that will get me back on the road. Thanks to all who viewed.

It's a 20-year-old truck; EVERYTHING needs maintenance, including the battery cable terminals. Click these & read the captions:

Awesome. Thanks for the links. It's easy to forget that having a rock-solid engine like our 7.3s doesn't mean they're not prone to wear and tear elsewhere.
