INSPECTION
ROTOR
(1) Check field coil for continuity. Check to ensure that there
is continuity between slip rings.
If resistance is extremely small, it means that there is
a short. If there is no continuity or if there is short circuit,
replace rotor assembly.
Resistance value : Approx. 3-5 Q
(2) Check field coil for grounding. Check to ensure that there
is no continuity between slip ring and core. If there is
continuity, replace rotor assembly.
STATOR
(1) Make continuity test on stator coil. Check to ensure that
there is continuity between coil leads.
If there is no continuity, replace stator assembly.
(2) Check coil for grounding. Check to ensure that there is
no continuity between coil and core. If there is continuity,
replace stator assembly.
RECTIFIERS
(1) Positive Rectifier Test
Check for continuity between positive rectifier and stator
coil lead connection terminal with a circuit tester. If there
is continuity in both directions, diode is shorted. Replace
rectifier assembly.
