CAUTION

Be careful not to score the heat protector by drill.
1. Use a 6.0 / diameter / mm drill to make a hole in the flange

of rivet as shown.

2. Break the rivet, and remove the rivet and heat protector.

HEAT PROTECTOR/RIVET INSTALLATION

Use a riveter to tighten the rivet by the following procedure.
1. Insert part A of rivet into the riveter, and insert the rivet into

the assembling area.

2. Operate the tool's handle while pushing the flange surface of

rivet by riveter. Part A of rivet is cut and the rivet is tightened.

CHARGING SYSTEM

GENERAL INFORMATION

M1161000101291

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.
