I'm not sure. My crystal ball is getting fuzzy and is not giving me a clear picture as to the make, model, or year of the vehicle in question. Perhaps you could help me out.
PCM is unable to regulate generator field current.
Check for 12 volts to alternator field. Check for open field in alternator; connections, brushes, alternator field winding continuity. Check wiring between alternator field and PCM. Possible bad PCM.
