1.

INSPECT ROTOR

(a) Check the rotor for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the slip rings.
Standard resistance: 2.1 - - 2.5 Ω at 20˚C (68˚F)
If there is no continuity, replace the rotor.
(b) Check the rotor for ground.
Using an ohmmeter, check that there is no continuity be-
tween the slip ring and rotor.
If there is continuity, replace the rotor.
(c) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(d) Using vernier calipers, 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.
2.

INSPECT STATOR (DRIVE END FRAME)

(a) Check the stator for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the coil leads.
If there is no continuity, replace the drive end frame assembly.
(b) Check the stator for ground.
Using an ohmmeter, check that there is no continuity be-
tween the coil lead and drive end frame.
If there is continuity, replace the drive end frame assembly.
