im an idiot. times a million.
brought truck to a alternator shop. the guy felt the pulley it was hot. very hot.
changed belts. tightened them up. (it was slipping)
tightened up loose ground on front battery.
everything is perfect now...

Thanks for letting us know how it turned out. That's what it sounded like. I'm guilty of doing the same thing. Over thinking the small stuff.

i was thinking no squeak. the belts gotta be fine. i was wrong. also i wasn't getting 14 volts when putting meter right to the alternator. i thought its gotta be the alternator. i was wrong. without the solid ground on on the battery it wont be pulling good voltage.... and im guessing it was worse in the cold because the belts would slip more or something
