6H-12 CHARGING SYSTEM
INSPECTION
ROTOR
1) Using ohmmeter, check for continuity between slip rings of
rotor. If there is no continuity, replace rotor.
Standard resistance between slip rings of rotor
: 2.7 – 3.1 Ω Ω Ω Ω at 20°C (68°F)
2) Using ohmmeter, check that there is no continuity between
slip ring and rotor. If there is continuity, replace rotor.
3) Check slip rings for roughness or scoring. If rough or scored,
replace rotor.
Using a vernier caliper, measure the slip ring diameter.
If the diameter is less than minimum, replace the rotor.
Slip ring diameter
Standard: 14.2 – 14.4 mm (0.557 – 0.567 in.)
Limit: 12.8 mm (0.504 in.)
STATOR
1) Using an ohmmeter, check all leads for continuity. If there is
no continuity, replace stator.
