A new battery and alternator were just installed 3 days ago because they both burnt out at the same time. Now today my charging system light came and I have no idea why? What could be the problem now?

Inspect the alternator belt tension-all connections on the battery and alternator-if okay could be a problem with the alternator field control from the computer

You need to triple check the charging system wiring connections-The PCM is not cheap-wrong move you'll end up having an extra one that you don't need-
