1. If the starter motor does not stop, inspect the following:
2. Check the starter magnetic switch

Magnetic Switch Pull-In Test

1. Disconnect the negative battery cable.
2. Remove the starter assembly from the vehicle.
3. Disconnect the field coil wire from the M-terminal of the magnetic switch.

   Fig. 1: Magnetic switch pull-in test connections

4. Connect a 12V battery between S-terminal and M-terminal on the magnetic switch of the starter.

   CAUTION
   The test must be performed quickly, in less than 10 seconds, to prevent the coil from burning.

5. If the pinion moves out, the pull-in coil is functioning properly. If it doesn't, replace the magnetic switch.

Magnetic Switch Hold-In Test

1. Disconnect the negative battery cable.
2. Remove the starter assembly from the vehicle.
3. Disconnect the field coil wire from the M-terminal of the magnetic switch.

4. Connect a 12V battery between S-terminal and body.

   CAUTION
   The test must be performed quickly, in less than 10 seconds, to prevent the coil from burning.

5. If the pinion remains out, everything is in order. If the pinion moves in, the hold-in circuit is open. Replace the magnetic switch.

Free Running Test

1. Disconnect the negative battery cable.
2. Remove the starter assembly from the vehicle.
3. Place the starter assembly into a vise with soft jaws. Connect a fully charged 12 volt battery to the starter motor as follows:
   1. Connect a test ammeter with 100 ampere scale and a carbon pile rheostat in series with battery positive post and starter motor terminal.
   2. Connect a voltmeter across the starter motor.
   3. Rotate the carbon pile to full-resistance position.

   4. Connect the battery cable from the negative battery post to the starter motor body.
   5. Adjust the rheostat until the battery voltage shown by the voltmeter is 11.5V for direct drive type starter, which are normally installed in 1.8L engines. On reduction-drive starters, which are normally installed in 2.0L engines, adjust the rheostat until the battery voltage shown by the voltmeter is 11.0 V.
   6. Confirm that the maximum amperage is within the specifications listed below and the starter turns freely.
   7. Direct drive starter — 60 Amps maximum
   8. Reduction drive starter — 90 Amps maximum
4. If the starter is not within specifications, replace the unit.

Magnetic Switch Return Test

1. Disconnect the negative battery cable.

   Fig. 4: Starter motor terminal identification — magnetic switch return test

2. Remove the starter assembly from the vehicle.
3. Disconnect the field coil wire from the M-terminal of the magnetic switch.
4. Connect a 12 volt battery between the M-terminal of the starter and the starter body.

   NOTE: This test must be done quickly, in less than 10 seconds, to prevent coil from burning.

5. Pull the pinion out and then release it. If the pinion quickly returns to its original position, everything is in order. If it doesn't, replace the magnetic switch.
