Starters: Diagnosis Kia Sorento I

TROUBLE SHOOTING

Note. See STARTER - GENERAL TROUBLE SHOOTING article in GENERAL INFORMATION.

Scheme 1

1. Using ohmmeter, check continuity between each insulated brush and plate. (Scheme 1)
2. Replace brush holder if there is continuity.

MAGNETIC SWITCH PULL-IN TEST

1. Disconnect the field coil wire from the "M" terminal of the magnetic switch.
2. Connect a 12V battery between the "S" terminal and the "M" terminal. see scheme 1
3. If the pinion moves out, then the pull-in coil is good. If it doesn't move out, replace the magnetic switch.

MAGNETIC SWITCH HOLD-IN TEST

1. Disconnect the field coil wire from the "M" terminal of the magnetic switch.
2. Connect a 12V battery between "S" terminal and the body.
3. If the pinion moves out, everything is in order. If the pinion moves back and forth repeatedly, the hold-in circuit is open. Then replace the magnetic switch.

FREE RUNNING TEST

1. Place the starter motor in a vise equipped with soft jaws and connect a fully-charged 12 volt battery to starter motor.
2. Connect a test ammeter (100-ampere scale) and carbon pile rheostat. (Scheme 2)
3. Connect a voltmeter (15-volt scale) across starter motor.
4. Rotate carbon pile to the off position.
5. Connect the battery cable from battery's negative post to the starter motor body.
6. Adjust until battery voltage shown on the voltmeter reads 11 volts.
7. Confirm that amperage is 90 amps or less at 2800 RPM or less, and that starter motor turns smoothly and freely.

Scheme 2

MAGNETIC SWITCH RETURN TEST

1. Disconnect field coil wire from the "M" terminal of the magnetic switch.
2. Connect a 12-volt battery between "M" terminal and the body.
3. Pull pinion out and release. If pinion returns quickly to its original position, everything is in order. If it doesn't, replace the magnetic switch.
