Alternator on Unit Test
(Before testing)
• Before alternator on unit test, check the battery terminal
connections, circuit connection, fan belt tension, charging
indicator lamp, fuses on the circuit, and abnormal noise from the
alternator.
• Prepare full charged battery for the test.
■
NOTE
• Be careful not to touch the rotating engine parts while
engine is running.
Keep safety distance from the engine rotating parts.
1. Start the engine.
2. When the engine is operating measure the voltage between two
battery terminals. If the voltage is between 13.8 V and 14.8 V,
the alternator is operating normally.
3. If the results of alternator on unit test are not within the
specifications, disassemble the alternator and check the each
component part for finding out the failure.

Fuel Cut Off Solenoid
1. Disconnect the connector.
2. Measure the resistance with an ohmmeter between the
connector terminals.
3. If the factory specification is not indicated the solenoid is faulty.
