Generator Output
WARNING: This page is about a different car, the 1997 Lexus SC 300. However, it is still accessible from the selected car via links, so may be relevant.
- Connect charging system test equipment as described in manufacturer's instructions. Check charging system output voltage at 2000 RPM. If output voltage is high, replace voltage regulator and retest. If output voltage is low, go to next step. If output voltage is correct, go to step 3). See GENERATOR OUTPUT SPECIFICATIONS table.
- If output voltage is low, by-pass regulator (full field generator) by grounding terminal "F" at back of generator. See Fig 1. Recheck charging system output voltage. If voltage now exceeds output voltage specified in GENERATOR OUTPUT SPECIFICATIONS table, replace regulator and recheck. If output voltage is still incorrect, repair or replace generator.
- With engine at 2000 RPM, place the heater blower switch on highest setting and turn on headlights (high beam). Ammeter reading should be 30 amps or more. If amperage output is incorrect, repair or replace generator.
