Starter Motor
4. Magnetic switch
Note: When the starter is flooded, be sure to
replace the magnetic switch with a new
one even if it does not have any
operational malfunction.
1- Conduction test for shunt coil
Check the conduction between the S
terminal and the switch body.
If there is conduction, it is a non-defective.
Figure 10-24
2- Conduction test for sheath coil
Check the conduction between the S
terminal and the M terminal.
If there is conduction, it is a non-defective.
Figure 10-25
3- Conduction test for contact
Place the plunger on the lower side and push
down the magnetic switch fully until the end.
At this time, check the conduction between
the B terminal and the M terminal.
If there is conduction, it is a non-defective.
Figure 10-26
5. Pinion clutch
1- Hold the clutch outer diameter and turn the
pinion by hand.
Inspect that the pinion turns smoothly when
turned in the drive direction, and the pinion
locks when turned in the anti-drive direction.
If there is any malfunction, replace it.
