(5) Engine Stop Solenoid
Connector Voltage
1. Disconnect the 2P connector from engine stop solenoid.
2. Turn the main switch key to the "ON" position.
3. Measure the voltage between the terminal 1 , terminal 2 and
body.
4. If the voltage differs from the battery voltage, the wiring harness
or main switch is faulty.

Stop Solenoid Coil
1. Disconnect the 2P connector from engine stop solenoid.
2. Measure the resistance between the terminal 1 , terminal 2 of
engine stop solenoid and body.
3. If resistance differs from the factory specifications, the coil is
faulty.

Engine Stop Solenoid Relay
1) Connector Voltage
1. Turn the main switch off.
2. Disconnect the engine stop solenoid relay (1).
3. Measure the voltage across the terminal
1 (Positive) and
chassis (Negative).
4. If the voltage differs from the battery voltage, the wiring harness
is faulty.
5. Turn the main switch on.
6. Measure the voltage across the terminal
3 (Positive) and
chassis (Negative).
7. If the voltage differs from the battery voltage, the wiring harness
is faulty.
2) Engine Stop Solenoid Relay
1. Remove the engine stop solenoid relay.
2. Apply battery voltage across terminals
1 and 2 , and check for
continuity across terminals 3 and 4 .
3. If continuity is not established across terminal 3 and 4 , replace
the engine stop solenoid relay.
