2) Using an ohmmeter, check that there is no continuity
between coil leads and stator core. If there is
continuity, replace coil assembly.
Brush and Brush Holder
Check each brush for wear by measuring its length (a)
as shown. If the brush is found worn down, replace the
brush.

Rectifier
1) Check continuity of rectifier by using an ohm meter.
2) Reverse the polarity of the tester probes and repeat
Step 1).
3) Check that one shows continuity and the other
shows no continuity.
If there is continuity, replace coil assembly.
Bearing
• Check that drive and bearing is not rough or worn.
• Check that end housing bearing is not rough or worn.
