Key Stop Solenoid - wsm STW37 Workshop Manual

STW34, STW37, STW40, WSM

(18) Key Stop Solenoid

Glow Plug Continuity
1. Disconnect the leads from the glow plugs.
2. Measure the resistance with an ohmmeter between the glow
plug terminal and chassis.
3. If 0 ohm is indicated, the screw at the tip of the glow plug and
the housing are short-circuited.
4. If the factory specification is not indicated, the glow plug is
faulty.
Glow plug resistance Factory specification
Connector Voltage
1. Disconnect the 2P connector from key stop solenoid.
2. Turn the main switch key to the "ON" position.
3. Measure the voltage with voltmeter between the terminal 1
(Black / White), terminal 2 (White / Black) 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 key stop solenoid.
2. Measure the resistance with an ohmmeter between the terminal
1, terminal 2 and body.
3. If resistance differs from the factory specification, the coil is
faulty.
