6D3–24 STARTING AND CHARGING SYSTEM
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.
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)
Rectifier Assembly
Check for continuity across "P" and "E" in the
range of multimeter.
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
066RS018
assembly.
IC Regulator Assembly
Check for continuity across "B" and "F" in the
range of multimeter.
Change polarity, and make sure that there is continuity in
one direction, and not in the reverse direction. In case of
066RS019
continuity in both directions, replace the IC regulator
assembly.
