6D3–18 STARTING AND CHARGING SYSTEM (6VD1 3.2L)

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., headlights). 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.
