Isuzu Rodeo UE. Manual - part 156

6D3–9

STARTING AND CHARGING SYSTEM (X22SE 2.2L)

Generator Power

1. Adjust load resistor, if the required load currents are

not attained.

2. The shape of the voltage curves on oscilloscope

curve should be regular.

3. Test value: 5 to 7A.
4. If the required minimum current intensity is not

attained, or if the oscilloscope picture shows
variations, the alternator should be overhauled.

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.

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

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.
