Alternator not charging.

You have a faulty alternator,oriellys test is not accurate.

I would agree except i have also installed a new alternator and im currently using the battery from his car.

I have the same problem. Took off the alternator and it checked out. Put in a new battery. Some days it runs ok, some days all the lights come on one by one and it will die. I haven’t checked from Batt to Alt for continuity yet, but it was suggest I may have a bad BCM. Bottom line: my alternator is getting the signal to barge the battery. Good luck

Yeah we ended up putting on a bcm and then the dealer couldn't figure out how to flash the bcm that said the battery was dead and that's why it would start and not charge. I don't know what they were doing he ended up scraping the car. But thanks for the help

I have 2007 Pontiac I reaplce battery and new alternator and still going dead battery what is my problem

I need and answer

check for blown fuses or relays??
