Isuzu D-Max / Isuzu Rodeo (TFR/TFS). Manual — part 817
6D3–22 STARTING AND CHARGING SYSTEM (6VD1 3.2L)
Inspection and Repair
Repair or replace necessary parts if extreme wear or
damage is found during inspection.
Rotor Assembly
1. Check the rotor slip ring surfaces for contamination
and roughness. If rough, polish with #500—600
sandpaper.
066RS014
2. Measure the slip ring diameter, and replace if it
exceeds the limit.
066RS015
3. Check resistance between slip rings, and replace if
there is no continuity.
066RS016
4. Check for continuity between slip ring and rotor core.
In case of continuity, replace the rotor assembly.
066RS017
6D3–23
STARTING AND CHARGING SYSTEM (6VD1 3.2L)
Stator Coil
1. Measure resistance between respective phases.
2. Measure insulation resistance between stator coil
and core with a mega–ohmmeter.
If less than standard, replace the coil.
066RS018
Brush
Measure the brush length.
If more than limit, replace the brush.
Standard: 10.mm (0.4134 in)
Limit: 8.4.mm (0.3307 in)
066RS019
Rectifier Assembly
Check for continuity across “P” and “E” in the
×
100W
range of multimeter.
066RW002
Change polarity, and make sure that there is continuity in
one direction, and not in the reverse direction. In case of
continuity in both directions, replace the rectifier
assembly.
IC Regulator Assembly
Check for continuity across “B” and “F” in the
×
100W
range of multimeter.
066RS021
Change polarity, and make sure that there is continuity in
one direction, and not in the reverse direction. In case of
continuity in both directions, replace the IC regulator
assembly.

Reassembly
To reassemble, follow the disassembly steps in the
reverse order, noting the following points:
1. Using a press with a socket wrench attached,
reassemble rotor and rear end cover assembly in the
front cover.
066RS022
2. Install pulley on the rotor.
Secure the pulley directly in the vise between two
copper plates, and tighten nut to the specified torque.
Torque: 111 N·m (11.3 kg·m/82 lb ft)
066RS010
Bench Test
Conduct a bench test of the generator.
066RS023
Preparation
Remove generator from the vehicle (see “Generator
removal”).
1. Secure generator to the bench test equipment and
connect wires.
Terminal “IG” for energization
Terminal “L” for neutral (warning lamp)
Terminal “B” for output
2. Conduct the generator characteristic test.
Characteristics of generator are shown in illustration.
Repair or replace the generator if its outputs are
abnormal.
