Generators & Regulators: Other Lexus LS III рестайлинг

BELT TENSION

Generator is driven by a serpentine drive belt. Belt tension is maintained by an automatic belt tensioner. No adjustment is necessary. For belt routing (Scheme 4)

Scheme 4

BRUSHES

1. Brushes should slide smoothly in holders. Replace brushes if damaged or worn. See «GENERATOR SPECIFICATIONS»(ref-167885-S08609192832004102500000) .
2. If exposed brush length is less than minimum, replace brushes and brush holder assembly. Install new brush springs when replacing brushes.

DIODES

Note. Information not available from manufacturer.

ROTOR

1. Check rotor for open field windings by using an ohmmeter across slip rings. Rotor resistance should be within specification. See «GENERATOR SPECIFICATIONS»(ref-167885-S08609192832004102500000) . If resistance reading is not as specified, replace rotor.
2. Check rotor for grounded field windings. Using an ohmmeter, check for continuity between slip ring and rotor. Continuity should not be present. If continuity is present, replace rotor.
3. Check slip rings for wear or pitting. If slip rings are rough, scored or less than minimum diameter, replace rotor.
