STATOR COIL ASSEMBLY
1. Check for continuity across the stator coils.
If there is no continuity, the stator coils must be
replaced.
Resistance Between The Terminal "N" and the Coil Ends

Standard
2. Check for continuity between each stator coils and the
stator core.
If there is continuity, the stator coils must be replaced.
BRUSH
Measure the length of the brush. If abrasion has reduced
the brush length to less than 6.5 mm, the brush must be
replaced with a new one.
A wear line is inscribed in the brush. If the line is not
visible, the brush must be replaced.
