1. Verify that the battery is fully charged.
2. Verify that the drive belt deflection/tension is within the specification.
3. Turn off all electrical loads.
4. Turn the ignition switch to START and verify that the generator turns smoothly without any noise while the engine is running.
5. Measure the voltage at the terminals shown in the table.
Standard voltage
6. Measure the current at terminal B.
Generated current (Reference)
7. If the voltage and/or current are not as specified, turn on the following electrical loads one by one. Verify that the current at generator terminal B increases accordingly.
^ Headlight
^ Blower motor
^ Rear window defroster
8. If not, disassemble and inspect the generator.
