1) Connector Voltage
1. Turn the main switch off.
2. Disconnect the engine stop solenoid relay.
3. Measure the voltage across the terminal A and chassis.
4. If the voltage differs from the battery voltage, slow blow fuse or wiring harness is faulty.
5. Set all levers to NEUTRAL position and turn the main switch on.
6. Measure the voltage across the terminal C and chassis.
7. If the voltage differs from the battery voltage, battery, slow blow fuse, safety switches, OPC timer or wiring harness is faulty.
2) Engine Stop Solenoid Relay
1. Measure the resistance across the terminal C and D.
2. If resistance notably differs from the factory specification, engine stop solenoid relay is faulty.
3. Apply battery voltage across the terminal C and D, and check for continuity across the terminal A and D.
4. If there is no continuity, engine stop solenoid relay is faulty.
