THE DUTY AT A/C ON




GENERATED ELECTRIC CURRENT CONTROL
The ECM detects the FR signal from the FR terminal of generator, computes the average duty rate and controls terminal G to control the generated electric current after determination of the generated current depended on the engine rate and FR duty, for the engine rate decrease prevention purpose at electrical loading.
