Alternator and Regulator System (14.02)
Description
The alternator installed to this vehicle is a Denso, SC1, 120
amp rating, with a 14.4 volt regulator.
The Alternator has an 'Altmon' signal that goes to and from
the PCM via a wire in the 3 way connector.
The 'Altmon' signal is monitored by the PCM which adjusts
ignition timing and fuelling if necessary to maintain idle
speed when the alternator is charging.
