1999 Dodge 2500 no altenator charge
Ok I know I have seen one do this before but can not remember what caused it and was wondering if anyone else has had this. 1999 Dodge 2500 altenator does not charge on the vehicle but test good on the bench.... I think it is in the pcm but can not remember ... thanks for your help Wayne

#1 cause in our shop is a bad PCM ground. There should be a ground cable from the side of the PCM to the body, clean both ends of the cable and a bit of paint off the body and 90% of the time you'll be fixed up ready to roll!
PS this is a very good cause of a no fault test on a tester. Load testing will sometimes cause pcm to properly regulate voltage. Just a thought.
