Generator Load Input

Generator Load Input (GLI) circuit is used by Powertrain Control Module (PCM) to determine generator load on engine. As generator load increases, PCM will adjust idle speed accordingly. This helps reduce idle surges due to switching high current loads. GLI signal is sent to PCM from voltage regulator/generator. GLI signal is a variable frequency duty cycle. Normal operating frequency is 40-250 Hz. Normal signal DC voltage (referenced to ground) is between 1.5 volts (low generator load) and 10.5 volts (high generator load).
