Shorted out big time
Well I was driving along today and my truck just shut off. No power to anything what-so-ever. Popped the hood, battery was smoking. Turns out the Positive cable from the starter solenoid had shorted against the exhaust. Apparently this wire had been in bad shape for some time. Tried to remove the cable from the solenoid and it was so corroded it broke the stud off. Question is, what should I check? I fear it fried the computer.

If it were me, I'd...
1. Smell around and look for burns as you try to detect other things that fried.
2. Pull fuses for anything expensive to repair or replace.
3. Put the power circuit back together and see what happens.
4. Replace the fuses one at a time and test the relevant items.
If you're worried about the computer you can unplug it first. But you won't know if it's damaged until you run with it. Odds are that the battery-starter-solenoid-ground circuit contained most of the damaging juice and everything else is probably ok.

Wow, luck was sure on your side since the battery didn't explode. Been there, done that, it wasn't pretty.
