ELECTRICAL SYSTEM 6-8
When the engine rpm become higher, the generated voltage of the AC generator also becomes higher and
the voltage between points � and � of the regulator accordingly becomes high, and when it reaches the
adjusted voltage of the control unit, consequently the control unit becomes "ON"condition. On the "ON"con-
dition 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 � to point �. Namely at the state of
this, the current 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 �, reverse 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.
