KUBOTA – L2501 – ELECTRICAL SYSTEM – CHECKING AND ADJUSTING – ENGINE STARTING AND STOPPING SYSTEM – Checking Starter Relay

1) Connector Voltage

1. Turn the main switch off.
2. Remove the starter relay.
3. Measure the voltage across the terminal C and chassis.
4. Measure the voltage across the terminal A and chassis while turn the main switch to START position.
5. If the voltage is different from the battery voltage, battery, slow blow fuse, wiring harness and main switch isย  ย  ย  ย  ย  ย  ย  ย  faulty.

2) Starter Relay
1. Measure the resistance across the terminal A and B.
2. If the resistance notably differs from the factory specifications, starter relay is faulty.
3. Apply battery voltage across the terminal A and B, and check for continuity across the terminal C and D.
4. If there is no continuity, starter relay is faulty.
