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.
