Kubota U17-3a Excavator 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. See the DISASSEMBLING AND ASSEMBLING and SERVICING for alternator.
