If the voltage is 13.5 or more with the engine running, there is a bad connection in the alternator. A symptom usually is that the battery slowly goes dead, however, the ammeter sometimes shows a positive charge.This is usually a bad diode in the alternator and less often a bad regulator. If this is the case, the alternator needs to be replaced.
