Many alternators have an internal voltage regulator. However, this vehicle's voltage is regulated via the PCM. What I recommend is to remove the alt and have it bench tested at a parts store. If it is good, then start checking wiring to see if there is a short or open circuit. If all wiring and alt check out good, suspect the PCM is bad.
