INSPECTION
1.
INSPECT ROTOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
slip rings.
Standard resistance (At 20
°
C (68
°
F): 2.8
−
3.0
Ω
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 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.
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 lead and drive end frame.
If there is continuity, replace the drive end frame assembly.
