6H-24 CHARGING SYSTEM
INSPECTION [70 A and 85 A types]
Rotor
_ Using ohmmeter, check for continuity between slip rings of rotor.
If there is no continuity, replace rotor.
Standard resistance: About 2.9 W
_ Using ohmmeter, check that there is no continuity between slip
ring and rotor. If there is continuity, replace rotor.
_ Check slip rings for roughness or scoring. If rough or scored, re-
place rotor.
Using a vernier caliper, measure the slip ring diameter.
Standard diameter: 14.2 – 14.4 mm (0.557 – 0.567 in.)
Minimum diameter: 12.8 mm (0.504 in.)
If the diameter is less than minimum, replace the rotor.
Stator
_ Using ohmmeter, check all leads for continuity. If there is no conti-
nuity, replace stator.
_ Using ohmmeter, check that there is no continuity between coil
leads and stator core. If there is continuity, replace stator.
