TESTING



If the starter motor does not operate at all, inspect the following:

  1. Check the starter coil
  2.  
  3. Check for poor contact at the battery terminal
  4.  
  5. If the starter motor does not stop, inspect the following:

    Check the starter magnetic switch
     

  6.  

Magnetic Switch Pull-In Test

See Figure 1

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the starter assembly from the vehicle.
  4.  
  5. Disconnect the field coil wire from the M-terminal of the magnetic switch.
  6.

Fig. Fig. 1: Magnetic switch pull-in test connections

  1. Connect a 12V battery between S-terminal and M-terminal on the magnetic switch of the starter.
  2.  


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

  1. If the pinion moves out, the pull-in coil is functioning properly. If it doesn't, replace the magnetic switch.
  2.  

Magnetic Switch Hold-In Test

See Figure 2

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the starter assembly from the vehicle.
  4.  
  5. Disconnect the field coil wire from the M-terminal of the magnetic switch.
  6.

  1. Connect a 12V battery between S-terminal and body.
  2.  


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

  1. If the pinion remains out, everything is in order. If the pinion moves in, the hold-in circuit is open. Replace the magnetic switch.
  2.  

Free Running Test

See Figure 3

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the starter assembly from the vehicle.
  4.  
  5. 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.  
    3. Connect a voltmeter across the starter motor.
    4.  
    5. Rotate the carbon pile to full-resistance position.
    6.  

  6.

Fig. Fig. 3: Starter motor free-running test connections

    1. Connect the battery cable from the negative battery post to the starter motor body.
    2.  
    3. 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.
    4.  
    5. Confirm that the maximum amperage is within the specifications listed below and the starter turns freely.

      Direct drive starter-60 Amps maximum
       
      Reduction drive starter-90 Amps maximum
       

    6.  


  1. If the starter is not within specifications, replace the unit.
  2.  

Magnetic Switch Return Test

See Figure 4

  1. Disconnect the negative battery cable.
  2.

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

  1. Remove the starter assembly from the vehicle.
  2.  
  3. Disconnect the field coil wire from the M-terminal of the magnetic switch.
  4.  
  5. Connect a 12 volt battery between the M-terminal of the starter and the starter body.
  6.  

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

  1. 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.
  2.  

REMOVAL & INSTALLATION



See Figures 5, 6, 7, 8, 9 and 10

  1. Disconnect the negative, then the positive battery cables from the battery.
  2.  
  3. For 1990-94 vehicles, remove the battery and battery tray from the engine compartment.
  4.  
  5. For 1990-94 vehicles, detach the speedometer cable connector from the transaxle.
  6.  
  7. For 1995-98 2.0L turbo engines, remove the air hose.
  8.  
  9. For 1995-98 2.4L engines, remove the air cleaner and air intake hose.
  10.  
  11. If equipped with 1.8L engine, remove the bracket on the lower side if the intake manifold.
  12.  
  13. Detach the starter motor electrical connections.
  14.
