bench tested alts

[choll]

Having an issue with the front battery charging. I followed the TM and everything is according to spec, as far as I can tell. I have changed the alt 3 times with alts that bench test ok. All the alts are out of CUCV's. Is it possible that the alts test ok and still are no good. Im only at 12.5 volts at the battery with the truck running. This thing is driving me nuts, I hate putting it on the battery charger every couple of days.

Sounds like your problem is not the alternator. did you test the 2 wires that plug into the alt? Does your dash light work?
