Highlander 4WD V6-3.0L (1MZ-FE) (2003)
7. INSPECT GENERATOR REGULATOR ASSY
a. Using an ohmmeter, check the continuity between terminals F and B.
Standard:
-
When the positive and negative poles between terminals F and B are exchanged, there is continuity in one way but no continuity in another
way.
-
If the continuity is not as specified, replace the voltage regulator.
b. Using an ohmmeter, check the continuity between terminals F and E.
Standard:
-
When the positive and negative poles between terminals F and E are exchanged, there is continuity in one way but no continuity in another
way.
-
If the continuity is not as specified, replace the voltage regulator.
8. INSPECT GENERATOR ROTOR ASSY
a. Inspect rotor for open circuit.
1. Using an ohmmeter, check that there is continuity between the slip rings.
Standard resistance: 2.1 - 2.5 ohm at 20 °C (68 °F)
If there is no continuity, replace the rotor.
