Charging System

General Description

The IC integral regulator charging system and its main
components are connected as shown in the 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
generator.

General On–Vehicle Inspection

The operating condition of charging system is indicated
by the charge warning lamp. The warning lamp comes on
when the starter switch is turned to “ON” position. The
charging system operates normally if the lamp goes off
when the engine starts.
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.
If lamp does not come on:
Disconnect wiring connector from generator, and
ground the terminal “L” on connector side.
If lamp comes on:
Repair or replace the generator.

Removal

1. Disconnect battery ground cable.
2. Move drive belt tensioner to loose side using wrench

then remove drive belt (1).

3. Disconnect the wire from terminal “B” and disconnect

the connector (4).

4. Remove generator fixing bolt (3).
5. Remove generator assembly (2).

Inspection

1. Disconnect the wiring connector from generator.
2. With the engine stopped, turn starter switch to “ON”

and connect a voltmeter between connector terminal
L (2) and ground or between terminal IG (1) and
ground.

If voltage is not present, the line between battery and
connector is disconnected and so requires repair.

3. Reconnect the wiring connector to the generator, run

the engine at middle speed, and turn off all electrical
devices other than engine.

4. Measure battery voltage. If it exceeds 16V, repair or

replace the generator.

5. Connect an ammeter to output terminal of generator,

and measure output current under  load by turning on
the other electrical devices (eg., head lights). At this
time, the voltage must not be less than 13V.

Installation

1. Install generator assembly to the position to be

installed.

2. Install generator assembly and tighten the fixing bolts

to the specified torque.

Torque:
M10 bolt: 41 N·m (4.2 Kg·m/30 lb ft)
M8 bolt: 21 N·m (2.1 Kg·m/15 lb ft)

3. Connect wiring harness connector and direct terminal

“B”.

4. Move drive belt tensioner to loose side using wrench,

then install drive belt to normal position.

5. Reconnect battery ground cable.
