Default P0622 Code and Battery light on!!

Man, I am stumped. I pulled the alt and had it tested at 2 locations. Tested good. The car is an 04 2.4 Turbo and it has 64,000 actual miles. I checked voltage at battery while running and its 12 V, but will drop slowly.. I pulled the positive off while running and it died... I Checked this fusible link between the starter and battery. Checked out good. Also, the fusible link from Alt to starter reads the same voltage as the top posts of the battery. The 2 prong connector has no juice at all at the Alt with it not running or running. Battery works fine in my other car also... I need some help guys.

i have the only PT on the forum that would run without a battery.

you likely have a bad wire to the PCM, or a bad PCM. grounding one of the wires on the alternators connector would make it charge....to test it anyways. leave it grounded and it'll overcharge and fry stuff

i can't tell you which wire though(because i don't know)

I would suggest checking to make sure the alternator wires are good and not hanging loose. Some members have found the wires disconnected or burnt.
