H O alternator

This vehicle is equipped with a Powertrain Control Module (PCM) controlled charging system. The PCM controlled charging system is a system whereby the PCM determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator. The PCM controlled charging system is unique in that it has two unidirectional communication lines between the PCM and the generator/regulator. Both of these communication lines are pulse-width modulated. The Generator Communication (GEN COM) line communicates the desired setpoint from the PCM to the voltage regulator and the Generator Monitor (GEN MON) line communicates the generator load and error conditions to the PCM. The third pin on the voltage regulator, the A circuit pin, is a dedicated battery voltage sense line.

these are complexed and if i had a cutsomer ask this qeustion i would recommend to bring it in to your local shop. i've never had to upgrade one of these but i would try it first and mearsure the amparge uotput when the system is aplying a load to the charging system. from what i read .it desides the output by monerting the demand on the alt. and adjust accordingly. what it doesn't say is if there is a limit for output. but just creates a setpoint for the conditions that are present. more requirment of amperage more it will let go. and visa versa. they do this to get optimal gas milage.

hopefully i helped and please let us know what becomes of this issue. lol
