– GENERATOR ASSY (1ZZ–FE/3ZZ–FE)
INSPECT GENERATOR ROTOR ASSY
Using an ohmmeter, check that there is continuity be-
tween the slip rings.
Standard resistance: 2.1 – 2.5 f at 20YC (68YF)
Using an ohmmeter, check that there is no continuity be-
tween the slip ring and rotor.
Using a vernier calipers, measure the slip ring diameter.
Standard diameter: 14.2 – 14.4 mm (0.559 – 0.567 in.)
Minimum diameter: 12.8 mm (0.504 in.)
INSPECT GENERATOR HOLDER W/RECTIFIER
Using an ohmmeter, connect one tester probe to the B or
E terminal and the other to each rectifier terminal.
Reverse the polarity of the tester probes and repeat step
(a).
Check that one shows continuity and the other shows no
continuity.
INSPECT GENERATOR BRUSH HOLDER ASSY
Using a vernier calipers, measure the exposed brush
length.
Standard exposed length:
9.5 – 11.5 mm (0.374 – 0.453 in.)
Minimum exposed length: 1.5 mm (0.059 in.)
