8-1. ELECTRIC SYSTEM

CHARGING SYSTEM

GENERAL
SYSTEM DESCRIPTION
The purpose of the charging system is to keep
the battery at a fuel state of charge and to
provide the electrical system with the required
electrical power for normal vehicle operation.
AC Generator
The AC generator is the primary source of
electrical energy. It transforms magnetic field
into electric current (AC).
The ACG has a 3 phase series stator.
Voltage Regulator/Rectifier
The rectifier receives AC current from the
magneto and transforms it into direct current
(DC).
The voltage regulator, included in the same unit,
limits voltage to prevent any damage to
electrical components.
Battery
The battery supplies DC power to the electric
starter for cranking the engine. During engine
starting, it also supplies DC power to the entire
electrical system.
At low engine RPM operation and high current
load conditions, it supplements the magneto
output and helps to maintain a steady system
voltage.
INSPECTION
CHARGING SYSTEM OUTPUT
First ensure that battery is in good condition
prior to performing the following tests.
