CHARGING SYSTEM

GENERAL DESCRIPTION

M1161000100629

The charging system charges the battery with the
generator output to keep the battery charged at a
constant level during varying electrical load.

OPERATION

Rotation of the excited field coil generates AC volt-
age in the stator.
This alternating current is rectified through diodes to
DC voltage having a waveform shown in the illustra-
tion above.
The average output voltage fluctuates slightly with
the generator load condition.

When the ignition switch is turned on, current flows in
the field coil and initial excitation of the field coil
occurs.
When the stator coil begins to generate power after
the engine is started, the field coil is excited by the
output current of the stator coil.
The generator output voltage rises as the field cur-
rent increases and it falls as the field current
decreases. When the battery positive voltage (gener-
ator S terminal voltage) reaches a regulated voltage
of approximately 14.4 V, the field current is cut off.
When the battery positive voltage drops below the
regulated voltage, the voltage regulator regulates the
output voltage to a constant level by controlling the
field current.
In addition, when the field current is constant, the
generator output voltage rises as the engine speed
increases.
