4) Check slip rings for roughness or scoring. If rough or
scored, replace the rotor.
Using a vernier caliper, measure the slip ring
diameter. If the diameter is less than minimum,
replace the rotor.
Slip ring diameter
Standard: 14.2 – 14.4 mm (0.560 – 0.566 in.)
Limit: 12.8 mm (0.503 in.)
Stator
1) Using an ohmmeter, check all leads for continuity. If
there is no continuity, replace the stator.
2) Using an ohmmeter, check that there is no continuity
between coil leads and stator core. If there is
continuity, replace the stator.
Brush and Brush Holder
Check each brush for wear by measuring its length as
shown. If the brush is found worn down to service limit,
replace the brush.
Exposed brush length "a"
Standard: 10.5 mm (0.41 in.)
Limit: 1.5 mm (0.05 in.)
Rectifier
1) Using an ohmmeter, connect one tester probe to the
"B" terminal (1) and the other to each rectifier
terminal (2).

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 the rectifier.
I2RH011A0014-01
4) Using an ohmmeter, connect one tester probe to
each negative terminal (1) and the other to each
rectifier terminal (2).
I2RH011A0015-01
5) Reverse the polarity of the tester probes and repeat
Step 4).
6) Check that one shows continuity and the other
shows no continuity.
If there is continuity, replace the rectifier.
