Generates an AC output, which is converted to a DC output by a rectifier assembly internal to generator, and is supplied to vehicle through the B+ terminal. S (stator) circuit is used to feed back a voltage signal from generator to regulator. This voltage (typically half battery voltage), is used by regulator to turn off indicator. Generator (10300) 0)Microprocessor 1)Rectifier 2)Stator 3)Regulator 4)Field 151–5, 151–7 A signal sent by the generator to the PCM indicating the elec- trical load that is placed on the generator to maintain the de- sired voltage set point. This signal is used to help the PCM determine the load placed on the engine by the charging sys- tem for idle speed control. The load is transmitted by means of a duty cycle, which is directly proportional to the load. RD 30-BA6 151–1 GEN COM C102a 3 A command signal sent by the PCM to the regulator indicating the desired voltage set point. TPS, ECT , IA T and VSS are among the inputs considered when calculating the voltage set point. The signal is transmitted by means of pulse trains that are communi- cated at least once every five seconds. The duty cycle of the pulse trains equates to the desired voltage set point.
