Magnetic Switch RTW46DSH005901

The following tests must be performed with the starter 3. Return Test
motor fully assembled.
The yoke lead wire must be disconnected from the “M”
terminal.
To prevent coil burning, complete each test as quickly
as possible (within three to five seconds).

Temporarily connect the solenoid switch between the
clutch and the housing and run the following test.
Complete each test within three to five seconds.

1. Pull-in Test
Connect the battery negative terminal with the
solenoid switch body and the M terminal. When
current is applied to the S terminal from the battery
positive terminal, the pinion should flutter.

Disconnect the battery positive lead at the S

terminal.

The pinion should return to its home position.

RTW46DSH004601

2. Hold-in Maintenance Test

Disconnect the lead at the M terminal. The pinion

should continue to flutter. RTW46DSH004701

during inspection.

Visual Check Glow Plug Resistance (Reference) Ohms

Check the main fuses and glow indicator for damage. Approximately 0.9
Replace the part(s) if required.

Glow Relay

The glow relay is located in the relay box the engine
compartment.

Use an ohmmeter to measure the resistance between
terminals No.2 and No.3.

If the measured value is outside the specified range, the
glow relay must be replaced.
