Alternator Inspection
1. Check for continuity of rotor coil. Check for continuity
between slip rings. Measure resistance of rotor
. If resis-
tance is low, it indicates a short circuit. If there is no conti-
nuity or a short circuit, replace the rotor assembly.
Resistance standard value 2.8 – 3.0 Ohms
Figure 105
2. Check rotor coil for ground. Make sure there is no
continuity between slip ring and core. If there is continu-
ity
, replace the rotor assembly.
Figure 106
3. Check stator for continuity. Make sure there is conti-
nuity between coil leads. If there is no continuity
, replace
the stator assembly.
Figure 107
4. Check coil for ground. Make sure there is no continu-
ity between the coil and core. If there is continuity
, re-
place the stator assembly.
