Generator Inspection [L3 With TC]: Generator: Current

NOTE:
  • Since the charging current decreases rapidly after starting the engine, perform the following procedure quickly, and read the maximum current value.
  1. Verify that the battery is fully charged.
    • Charge if necessary.
  2. Verify that the drive belt deflection/tension is within the specification. (See DRIVE BELT INSPECTION [L3 WITH TC] ).
  3. Disconnect the negative battery cable.
  4. Connect a tester, which can read 120 A or more  , between generator terminal B and the wiring harness.
  5. Turn off all electrical loads.
  6. Start the engine and increase the engine speed to 2,000-2,500 RPM. 
  7. Turn the following electrical loads on and verify that the current reading increases.
    1. Headlights
    2. Blower motor
    3. Rear window defroster
      • If generator terminal B current does not increase, repair or replace the generator if necessary.
      NOTE:
      • Current required for generating power varies with the electrical loads applied.

    Generator generated current (reference value) [Conditions] Ambient temperature: 20°C {68°F}, Voltage: 13.5 V, Engine hot
