Inspection After Assembly

Use a vernier caliper to measure the pinion shaft thrust
play.
The pinion shaft thrust play is equal to the pinion shaft end
and pinion stopper clearance.

MAGNETIC SWITCH

The following tests must be performed with the starter
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).

RTW46DSH004601

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.

RTW46DSH005901

2. Hold-in Maintenance Test

Disconnect the lead at the M terminal. The pinion should
continue to flutter.

RTW46DSH004701

3. Return

Test

Disconnect the battery positive lead at the S terminal.
The pinion should return to its home position.

INSPECTION AND REPAIR

Make the necessary adjustments, repairs, and part replacement if excessive wear of damage is discovered during
inspection.

VISUAL CHECK

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

GLOW RELAY

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

825R300046

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.
