Hello...... I have a 2003 Escalade ESV. Im getting a "battery not chargeing" message on intrument cluster screen. I had both the battery and altinator tested and they checked out fine. Just wandering what could be causeing this issue. Any help would be much appreciated. Thanks in advance.

There is a connector on the back of the alternator I would check and see if it's loose or disconnected

The pcm controls the alternator's voltage regulator
