INSPECTION
1. INSPECT ROTOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
slip rings.
Standard resistance:
2.8 − 3.0 Ω at 20°C (68°F)
If there is no continuity, replace the rotor.
2. INSPECT ROTOR FOR GROUND
Using an ohmmeter, check that there is no continuity between
the slip ring and rotor.
If there is continuity, replace the rotor.
3. INSPECT SLIP RINGS
(a) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(b) Using vernier calipers, measure the slip ring diameters.
Standard diameter:
14.2 − 14.4 mm (0.559 − 0.567 in.)
Minimum diameter:
12.8 mm (0.504 in.)
4. INSPECT STATOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
coil leads.
If there is no continuity, replace the drive end frame assembly.
5. INSPECT STATOR FOR GROUND
Using an ohmmeter, check that there is no continuity between
the coil leads and drive end frame.
If there is continuity, replace the drive end frame assembly.

6. INSPECT EXPOSED BRUSH LENGTH
Using vernier calipers, measure the exposed brush length.
Standard exposed length:
10.5 mm (0.413 in.)
Minimum exposed length:
1.5 mm (0.059 in.)
If the exposed length is less than minimum, replace the
brushes.
7. IF NECESSARY, REPLACE BRUSHES
(a) Unsolder and remove the brush and spring.
(b) Run the wire of the brush through the hole in the brush
holder, and insert the spring and brush into the brush
holder.
(c) Solder the brush wire to the brush holder at the exposed
length.
Exposed length:
10.5 mm (0.413 in.)
(d) Check that the brush moves smoothly in the brush holder.
(e) Cut off the excess wire.
(f) Apply insulation paint to the soldered point.
8. INSPECT POSITIVE RECTIFIER
(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.
9. INSPECT NEGATIVE RECTIFIER
(a) Using an ohmmeter, connect one tester probe to each
negative (−) terminal and the other to each rectifier termi-
nal.
(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.
