OK so I have fault code 0622, Generator field circuit fault. I have a new battery and tried replacing the alternator with one from Oreilly's and Advanced Auto. Both of the alternators I have bought have failed when tested. When I put the alternator in it will run for a little bit and then I get a "Check charging system" message. A guy from a local performance shop said to order a PA from AM, which I did today. He also said it is not unusual for the Major chains to stock faulty rebuilt alternators.

I have checked all the wiring, replaced all grounds, and check the alternator cable. They are all good. I'm just wondering if anybody else has ever had this problem so I can feel a little better about all this BS I've been through. ANy advice would be greatly appreciated.
