Stranger things have happened. If you have voltage at the red wire in the plastic connector and the ground you should be charging. This is a Delco alternator right? If so pull the plastic connector and put it to full field to test it.
Wayyy back in the day on the L/N JB's we would sometimes have to flash the field first time out. Bad alt out of the box? Not usually. I suppose it could happen. What was your original issue? Reman or New? Bosch, LN, Delco-Remy?
