3) Fuel Cut Off Solenoid Resistance
1. Disconnect the connector of fuel cut-off solenoid.
2. Measure the resistances with an ohmmeter across the
terminal 3 (white) and terminal 2 (black), across the terminal
1 (red) and terminal 2 (black).
3. If the resistances are 0 ohm or infinity, fuel cut-off solenoid is
faulty.
Fuel Cut Off Solenoid
1) Lead Terminal Voltage
1. Disconnect the connector of fuel cut-off solenoid.
2. Turn the main switch "ON".
3. Measure the voltage with voltmeter across the terminal 3
(red, black)
ofthe wiring harness side and the chassis.
4. If the battery voltage (11 to 14 V) is not indicated, the fuse,
the main switch or
wiring harness are faulty.

2) Fuel Cut Off Solenoid Test
1. Disconnect the lead from the fuel cut off solenoid after
turning the main switch off.
2. Connect jumper leads from the battery positive terminal to
the fuel cut off solenoid terminal 1 (red), and from the
battery negative terminal to the fuel cut off solenoid
terminal 2 (black).
3. If the solenoid plunger is not attracted, the fuel cut off
solenoid is faulty.
