1E – 20  ENGINE ELECTRICAL

D102E704

D

Inspect the pinion gear’s moving to the outside (2).

D

If the pinion gear does not move outside, replace
the magnetic switch.

D102E705

4. Solenoid hold-in test.

D

Disconnect the starter motor terminal M (1).

D

Connect the 12-volt battery lead to the starter mo-
tor terminal S and body.

Notice: Complete the testing in a minimum amount of
time to prevent overheating and damaging the solenoid.

D102E706

D

Check the pinion gear’s moving to the outside (2).

D

If the pinion gear move to the inside, the circuit is
open. Replace the magnetic switch.

D102E707

5. Solenoid return test.

D

Disconnect the starter motor terminal M (1).

D

Connect the 12-volt battery lead to the starter mo-
tor terminal S and body.

Notice: Complete the testing in a minimum amount of
time to prevent overheating and damaging the solenoid.

D102E708

D

Check the returning speed of pinion gear (2).
If the returning speed is fast, the operation is nor-
mal.

D

Replace the solenoid if the operation is abnormal.

D102E709

5. No-road test.

D

Connect the 12-volt battery lead to the starter cir-
cuit.

D

Connect the current and the voltage (1).

D

Install the starter motor rpm gage (2).

D

Start the starter motor with the switch on (3).

D

Measure the speed of pinion gear and the current.

D

If the measurement satisfy the limit, the starter mo-
tor is normal.

Inspection / Measurement
(After the Overhaul)

1. Ground test for armature coil.

D

Inspect the insulation between commutator and ar-
mature coil using the voltmeter.

D

Replace the armature assembly if necessary.

D102E717

2. Short circuit test for armature coil.

D

If test equipment is available, check the armature
for short circuit by placing it on a growler, and hold-
ing back a saw blade over the armature core while
the armature is rotated. If the saw blade vibrates,
replace the armature.

D102E718

3. Open circuit test for armature coil.

D

Check the continuity between the commutator
bars using multimeter.

D

Replace the armature assembly if necessary.

D102E719

4. Inspect the brushes wear.

D

Inspect the brushes, the pop-out springs and the
brush holder for wear and damage. Replace the
brushes, if necessary.
