Removal & Installation




NOTE
Disable the air suspension before raising the vehicle. The switch is located on the left side of the luggage compartment.

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Turn the air suspension switch to the OFF position.
  4.  
  5. Remove or disconnect the following:

    Negative battery cable
     
    Radiator splash shield
     
    Starter solenoid connections
     
    Starter
     

  6.  

To install:

  1. Install or connect the following:

    Starter. Tighten the bolt and stud to 15-20 ft. lbs. (20-27 Nm).
     
    Starter solenoid connections
     
    Radiator splash shield
     
    Negative battery cable
     

  2.  
  3. Turn the air suspension switch to the ON position.
  4.  

  1. Disconnect the negative battery cable.
  2.  
  3. Raise the vehicle and support it safely.
  4.  
  5. Disconnect the starter cable from the starter. If equipped with starter mounted solenoid, disconnect the push-on connector from the solenoid.
  6.  


NOTE
To disconnect the hard-shell connector from the solenoid S terminal, grasp the plastic shell and pull off; do not pull on the wire. Pull straight off to prevent damage to the connector and S terminal.

  1. Remove the starter bolts and the starter.
  2.  


NOTE
Some 3.8L applications have a starter-mounting stud that is used for engine ground. Ensure this connection is tight when replacing a starter.

To install:

  1. Position the starter to the engine and tighten the mounting bolts to 15-20 ft. lbs. (20-27 Nm).
  2.  
  3. Reconnect the electrical leads. Connect the negative battery cable.
  4.

Testing & Troubleshooting



Feed Circuit Test
  1. Make sure the battery is fully charged.
  2.  
  3. Disconnect the Inertia Fuel Shutoff (IFS) switch.
  4.  
  5. Connect a remote starter switch between the starter solenoid S-terminal and the battery positive (+) terminal.
  6.  
  7. Connect the Rotunda 73 Digital Multimeter positive lead to the battery positive (+) post. Connect negative lead to the starter solenoid M-terminal.

  10.  
  11. Engage the remote starter switch. Read and record the voltage. The voltage reading should be 0.5 volts or less.
  12.  
  13. If the voltage reading is 0.5 volts or less, go to the Starter Motor-Motor Ground Circuit Component Test.
  14.  
  15. If the voltage reading is greater than 0.5 volts, indicating excessive resistance, move the Rotunda 73 Digital Multimeter negative lead to the starter solenoid B-terminal and repeat the test. If the voltage reading at the B-terminal is lower than 0.5 volts, the concern is either in the connections at the starter solenoid or in the solenoid contacts.
  16.  
  17. Remove the cables from solenoid B-, S- and M-terminals. Clean the cables and connections and reinstall the cables to the proper terminals. Repeat Steps 3 through 6. If the voltage drop reading is still greater than 0.5 volts when checked at the M-terminal or less than 0.5 volts when checked at the B-terminal, the concern is in the solenoid contacts. Replace the starter motor.
  18.  
  19. If the voltage reading taken at the solenoid B-terminal is still greater than 0.5 volts after cleaning the cables and connections at the solenoid, the concern is either in the positive (+) battery cable connection or in the positive battery cable itself.
  20.  
  21. By moving the Rotunda 73 Digital Multimeter negative lead toward the battery and checking each mechanical connection point, the excessive voltage drop can be located. When the high reading disappears, the last mechanical point that was checked is the concern. Repair or replace this connection as required.
  22.  

Ground Circuit Test

A slow cranking condition can be caused by resistance in the ground or return portion of the cranking circuit. Check the voltage drop in the ground circuit as follows:

  1. Disconnect the inertia fuel shutoff switch.
  2.  
  3. Connect a remote starter switch between the starter solenoid S-terminal and the battery positive (+) terminal.
  4.  
  5. Connect the Rotunda 73 Digital Multimeter positive lead to the starter motor housing (the connection must be clean and free of rust or grease). Connect the negative lead to the negative (-) battery terminal.

  6.  
  7. Engage the remote starter switch and crank the engine. Read and record the voltage reading. The reading should be 0.2 volts or less.
  8.  
  9. If the voltage drop is more than 0.2 volts, clean the negative cable connections at the battery and body connections, and retest.
  10.  
  11. If the voltage drop is greater than 0.2 volts, determine which way the current is flowing in the cable.
  12.  
  13. Connect the Rotunda 73 Digital Multimeter positive lead to the end of the cable nearest battery positive.
  14.  
  15. Connect the multimeter negative lead to the terminal at the other end of the cable.
  16.  
  17. Crank the engine and observe the voltage reading. The voltage reading should be 0.2 volts or lower. If the voltage drop is too high, clean the terminal ends. Retest, and if still high, replace the cable. If the voltage reading is less than 0.2 volts and the engine still cranks slowly, replace the starter motor.
  18.  

Voltage Drop Test

WARNING
When servicing the starter motor or performing other underhood work in the vicinity of the starter motor, be aware that the heavy gauge battery input lead at the starter solenoid is "electrically hot" at all times.


WARNING
A protective cap or boot is provided over the battery input terminal on all vehicle lines and must be replaced after servicing. Be sure to disconnect the battery ground cable before servicing the starter motor.

Always make the Rotunda 73 Digital Multimeter connections at the component terminal rather than at the wiring end connector. Making a connection at the wiring end connector could result in false readings because the meter will not pick up a high resistance between the wiring connector and the component.


NOTE
The battery must be in good condition and fully charged prior to performing this test.

  1. Disable the ignition system by unplugging the coil pack. Verify that the vehicle will not start.
  2.  
  3. Connect a voltmeter between the positive terminal of the battery and the starter B+ circuit.
  4.  
  5. Turn the ignition key to the START position and note the voltage on the meter.
  6.  
  7. If voltage reads 0.5 volts or more, there is high resistance in the starter cables or the cable ground, repair as necessary. If the voltage reading is ok proceed to the next step.
  8.  
  9. Connect a voltmeter between the positive terminal of the battery and the starter M circuit.
  10.  
  11. Turn the ignition key to the START position and note the voltage on the meter.
  12.  
  13. If voltage reads 0.5 volts or more, there is high resistance in the starter. Repair or replace the starter as necessary.
  14.  


NOTE
Many automotive parts stores have starter bench testers available for use by customers. A starter bench test is the most definitive way to determine the condition of your starter.
