Isuzu D-Max / Isuzu Rodeo (TFR/TFS). Manual - part 815

6D3–14 STARTING AND CHARGING SYSTEM (6VD1 3.2L)

If the measured value is out of standard, insert dust cover,
or disassemble and adjust.

Characteristic Test

For easily confirming the characteristics, conduct the no
load test as follows:
Rating as short as 30 seconds requires rapid testing.
Fix the starter on the test bench, and wire as shown in
illustration. When the switch is closed, the current flows
and the starter runs under no load. At this time, measure
current, voltage and speed to check if they satisfy the
standard.

Charging System

General Description

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