4. INSPECT SLIP RINGS
(a) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(b) Using a vernier caliper, measure the slip ring diameter.
Standard diameter:
14.2 − 14.4 mm (0.559 − 0.567 in.)
Minimum diameter:
12.8 mm (0.504 in.)
If the diameter is less than minimum, replace the rotor.

5. INSPECT STATOR (DRIVE END FRAME) FOR OPEN
Ohmmeter
CIRCUIT
Using an ohmmeter, check that there is continuity between the
coil leads.
If there is no continuity, replace the drive end frame assembly

6. INSPECT STATOR (DRIVE END FRAME) FOR
Ohmmeter
GROUND
Using an ohmmeter, check that there is no continuity between
the coil lead and drive end frame.
If there is continuity, replace the drive end frame assembly

7. INSPECT EXPOSED BRUSH LENGTH
Using vernier calipers, measure the exposed brush length.
Standard exposed length:
9.5 ∼ 11.5 mm (0.374 ∼ 0.453 in.)
Minimum exposed length:
1.5 mm (0.059 in.)
If the exposed length is less than minimum, replace the brush
holder assembly.

8. INSPECT POSITIVE RECTIFIER HOLDER
(a) Using an ohmmeter, connect one tester probe to the posi-
tive (+) terminal and the other to each rectifier terminal.
(b) Reverse the polarity of the tester probes and repeat step
(a).
(c) Check that one shows continuity and the other shows no
continuity.
If continuity is not as specified, replace the rectifier holder.
