6D3-2 CHARGING SYSTEM

GENERAL DESCRIPTION

The charging system is the IC integral regulator charging system and its main components are connected as shown
in figure.
The regulator is a solid state type and it is mounted along with the brush holder assembly inside the generator in-
stalled on the rear end cover.
The generator does not require particular maintenance such as voltage adjustment. The rectifier connected to the
stator coil has nine diodes to transform A.C. voltage into D.C. voltage. This D.C. voltage is connected to the output
terminal of generator.
