When the engine rpm become higher, the generated voltage of the AC generator also becomes higher and the
voltage between points
voltage of the control unit, consequently the control unit becomes ON condition. On the ON condition of the
control unit, signal will be sent to the SCR (Thyristor) gate probe and SCR will become ON condition. Then
the SCR becomes conductive to the direction from point
generated from the AC generator gets through SCR without charging the battery and returns to the AC generator
again. At the end of this state, since the AC current generated from the AC generator flows into the point
current tends to flow to SCR, then the circuit of SCR turns to OFF mode and begins to charge the battery again.
Thus these repetitions maintain charging constant voltage to the battry and protect it from overcharging.
