The circuit of Suzuki GSX1300 Hayabusa composed of generator, regulator/rectifier unit and battery. The AC current generated from the generator is rectified by the rectifier and is turned into DC current, then it charges the battery. While the engine rpm is low and the generated voltage of generator is lower then the adjusted voltage of regulator, the regulator does not function. However, the generated current charges the battery directly at this time.

When the engine rpm becomes higher, the generated voltage of the generator also becomes higher and the voltage between the battery terminals becomes high accordingly. When it reaches the adjusted voltage of the integrated circuit and it is turned “ON”, a signal will be sent to the SCR (thyristor) gate probe and the SCR will be turned “ON”. Then the SCR becomes conductive in the direction from point A to point B. At this time the current generated from the generator gets through the SCR without charging the battery and returns to generator again.
