Just wondering if there is a common place to look for the short or any advice.
Thanks!

Assuming you don't have this fixed yet, can you describe what "won't charge" means here? I'm assuming your battery is flat and wont start the truck?
How old is the battery? Did you fully charge it before doing any of these tests?
It should be charged at 12.4-8 volts.
I find that they key to diagnosing problems is: 1. be clear on what you assume 2. do the easy stuff first
So you're assuming the battery is ok. Have you had that tested?
My 1991 burb "wouldn't start" but instead of saying that, I said "it has a bad battery". Which I replaced (probably not a bad idea), only to find out the problem persisted! It was a bad starter.
Make sure you cover the basics, then we can go back to wiggling wires!
