z After installing a belt, check that it fits properly in the ribbed grooves. z Check with your hand to confirm that the belt has not slipped out of the groove on the bottom of the pulley. z After installing a new belt, run the engine for about 5 min- utes and recheck the belt tension. 6. VISUALLY CHECK GENERATOR WIRING AND LIS- TEN FOR ABNORMAL NOISES (a) Check that the wiring is in good condition. (b) Check that there is no abnormal noise from the generator while the engine is running. 7. CHECK DISCHARGE WARNING LIGHT CIRCUIT (a) Warm up the engine and then turn it off. (b) Turn off all accessories. (c) Turn the ignition switch ”ON”. Check that the discharge warning light is lit. (d) Start the engine. Check that the light goes off. If the light does not go off as specified, troubleshoot the dis- charge light circuit.

P14228 Terminal F CH–4 – CHARGING CHARGING SYSTEM 1008 AuthorĂ: DateĂ: 1997 LEXUS ES300 (RM511U) 9. INSPECT CHARGING CIRCUIT WITH LOAD (a) With the engine running at 2,000 rpm, turn on the high beam headlights and place the heater blower switch at ”HI”. (b) Check the reading on the ammeter. Standard amperage: 30 A or more If the ammeter reading is less than the standard amperage, re- pair the generator. HINT: If the battery is fully charged, the indication will sometimes be less than standard amperage.
