STARTER INSPECTION [MZI-3.7]

ON-VEHICLE INSPECTION

1. Verify that the battery is fully charged.

2. The starter is normal if it rotates smoothly and without any noise when the engine is cranked.



If the starter does not operate, inspect the following:



Remove the starter, and inspect the starter unit.



Inspect the related wiring harnesses, the ignition switch, and the transaxle range switch.

NO-LOAD TEST

1. Verify that the battery is fully charged.

2. Connect the starter, battery, and a tester as shown in the figure.

3. Operate the starter and verify that it rotates smoothly.



If the starter does not rotate smoothly, inspect the starter unit.

4. Measure the voltage and current while the starter is operating.

MAGNETIC SWITCH OPERATION INSPECTION

Pull-out test

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.

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.
