GENERATOR FR TERMINAL
Generator turns ON/OFF the power transistor in the voltage
regulator to adjust current flow in the field coil according to
alternator output current. In this way generator's output voltage
is kept adjusted (to about 14.7 V). The ratio of power transistor
ON time (ON duty) is output from generator FR terminal to
ECM. ECM uses this signal to detect generator's output current
and drives throttle actuator control motor according to output
current (electric load). This prevents change in idle speed due
to electric load and helps maintain stable idle speed.
