General Description
The charging system is an IC integral regulator charging
system and its main components are connected as
shown in illustration.
The regulator is a solid state type and it is mounted along
with the brush holder assembly inside the generator
installed on the rear end cover.
The generator does not require particular maintenance
such as voltage adjustment. The rectifier connected to
the stator coil has eight diodes to transform AC voltage
into DC voltage.
This DC voltage is connected to the output terminal of

If the warning lamp shows abnormality or if undercharged
or overcharged battery condition is suspected, perform
diagnosis by checking the charging system as follows:
1. Check visually the belt and wiring connector.
2. With the engine stopped, turn the stator switch to
"ON" position and observe the warning lamp.
