Solenoid Valves

1) Connector Voltage

1. Remove the connector (1).

2. Turn on the main switch, PTO switch, 4WD switch or rear

differential lock switch at ON position.

3. Measure the voltage across the each terminal and chassis.

4. If the voltage differs from battery voltage, the wiring harness, fuse

or main switch is faulty.

Each terminal –

2) Solenoid Valve

1. Disconnect the wire harness connector (1).

2. Measure the resistance with an ohmmeter across the each

terminal 1/2/3 on the connector (1) and chassis.

3. If infinity is indicated, the solenoid valve is faulty.
