Sienna LE V6-3.0L (1MZ-FE) (1998)
4. INSPECT STATOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the coil leads.
If there is no continuity, replace the drive end frame assembly.
5. INSPECT STATOR FOR GROUND
Using an ohmmeter, check that there is no continuity between the coil lead and drive end frame.
If there is continuity, replace the drive end frame assembly.
6. INSPECT EXPOSED BRUSH LENGTH
Using a vernier caliper, measure the exposed brush length.
Standard exposed length: 10.5 mm (0.413 in.)
Minimum exposed length: 1.5 mm (0.059 in.)
If the exposed length is less than minimum, replace the brushes and brush holder assembly.
7. INSPECT POSITIVE RECTIFIER
a. Using an ohmmeter, connect one tester probe to the positive (+) terminal and the other to each rectifier terminal.
b. Reverse the polarity of the tester probes and repeat step (a).
c. Check that one shows continuity and the other shows no continuity.
If continuity is not as specified, replace the rectifier holder.
