MAGNETIC SWITCH OPERATION INSPECTION
Pull-out test
NOTE:
Depending on the battery charge condition, the starter motor pinion may
rotate while in an extended state. This is due to current flowing to the
starter motor through the pull-in coil to turn the starter motor, and does
not indicate an abnormality.
1. Verify that the starter motor pinion is extended while battery positive voltage is connected to terminal S
and the starter body is grounded.
If the starter motor pinion is not extended, repair or replace the starter.

2. Connect battery positive voltage to terminal M and ground the starter body.
3. Pull out the drive pinion with a screwdriver. Verify that it returns to its original position when released.
If it does not return, repair or replace the starter.
