Generator Inspection: Generator: Current

NOTE:

Since the charging current decreases rapidly after starting the engine, perform the following procedure quickly, and read the maximum current value.

Verify that the battery is fully charged.
- Charge if necessary.
Verify that the drive belt deflection/tension is within the specification. (L3) (See DRIVE BELT INSPECTION [L3] .)
Disconnect the negative battery cable.
Connect a tester cable of reading 120 A or more between generator terminal B and the wiring harness.
Turn off all electrical loads.
Start the engine and increase the engine speed to 2,000-2,500 rpm.

Turn the following electrical loads on and verify that the current reading increases.

Headlights
Blower motor
Rear window defroster
- If generator terminal B current does not increase, repair or replace the generator if necessary.

NOTE:
