not a diy, moved, made title more descriptive

check for damaged, broken, melted wiring under the hood that the belt may have damaged, sounds like maybe a ground issue

Unbolt the battery and verify the thick wire going into the alternator didn’t get yanked out of the back of the alternator.

Recheck that both the alternator 12mm mounting bolts are good and tight.

I bet you didn't tighten all of the alternator bolts.
Doing so can quickly cause permanent damage to the PCM.

But I did, had to loosen them to replace the belt w/o AC then tighten them back up, then rechecked after started the engine run for few mins then shut off
