1J-11 Charging System:
Rotor Coil Continuity Check
Measure the continuity between the two slip rings (1) on
the rotor coil using a tester.
If there is no continuity, replace the rotor.
Also check that the rotor is properly insulated.
Slip Rings
If the slip rings are dirty, polish them with #400
sandpaper and wipe them using a clean, dry cloth.
Then, measure the slip ring O.D. using vernier calipers.
If it is less than the service limit, replace the slip rings
with new ones.
Special tool
(A): 09900–20102 (Vernire calipers)
Slip ring O.D.
Service limit: 14.0 mm (0.55 in)
Carbon Brush
Measure the length "a" of the carbon brushes as shown.
If the measurement is less then the service limit, replace
the carbon brushes with new ones.
Brush length "a"
Service limit: 4.5 mm (0.18 mm)
