[QUOTE="TooManyToys, post: 1549500, member: 30841"] Depending on the alternator, several different voltage regulators could have been installed. If the VR is one with a higher voltage setpoint than 14.4v, even with a lower output current alternator, you could get the GPCM to cycle on and off due to the voltage. The details from the service manual how the system works, and three graphs showing the voltages you can expect from different setups you've mentioned. [/QUOTE]
