General InformationGeneral 1. Basically, all measurements in this manual are taken with a tracking gauge. 2. When a measuring tape is used, check to be sure there is no elongation, twisting or bending...
Circuit Diagram • COM signal - When controlling the voltage generated, the ECM sends the target voltage data to the alternator via a PWM signal.(High voltage: 4V or higher, low voltage: 2V or lower) • FR signal - The transistor activation signal inside the alternator monitors the voltage generated by the alternator to control the excitation current before it sends the FR signal to the ECM...
