This sort of thing happened to my truck a few years back. Check the main alt charge wire for any melted spots. https://www.yotatech.com/forums/f131/lights-out-266855/

so i think i found the problem. while back i bought a new alternator from O,Reillys and turns out that they sold me the wrong alternator! It was pushing 70amps instead of 60amps and it fried some of my electrical componiates! Im pretty pissed at O'reillys right now! It was an alternator for an automatic in instead of a manual.

Concur with rworegon.
Higher amp alternator will not cause it. However an alternator with shorts (Auto-parts store sell bad alternators once in while, correct?) could.
Disconnect battery cables.
Disconnect "B" wire from aternator screw post. Measure resistance from screw post to ground. try to rotate alternator if possible. resistance should read in meg-ohms. Lower than that means shorted winding or rectifier.
Cheers!
