CHARGING SYSTEM (See P.B-84.)

OPERATION
When engine is stationary
D

When the ignition switch is turned to the ON

position, current flows the alternator L terminal

and, at the same time, the charge warning lamp

illuminates.

When engine is started and after engine has

started
D

When the engine is started, the charge warning

lamp goes out because of the charging voltage

begin applied to the alternator L terminal.

D

The battery voltage being applied to the

alternator S terminal is monitored by the voltage

regulator. Therefore, the amount of electricity

produced by the alternator is controlled by

allowing and cutting off the current flowing to

the field coil.

D

The alternator B terminal supplies power to

each load.
