Testing



Starter Feed Circuit

CAUTION
The ignition system must be disabled to prevent engine start while performing the following tests.

  1. Connect a volt-ampere tester (multimeter) to the battery terminals.
  2.  
  3. Disable the ignition system.
  4.  
  5. Verify that all lights and accessories are off, and the transaxle shift selector is in Park (automatic) or Neutral (manual). Set the parking brake.
  6.  
  7. Rotate and hold the ignition switch in the START position. Observe the volt-ampere tester:
    WARNING
    Do not overheat the starter motor or draw the battery voltage below 9.6 volts during cranking operations.



    If the voltage reads above 9.6 volts, and the amperage draw reads above 250 amps, go to the starter feed circuit resistance test (following this test).
     
    If the voltage reads 12.4 volts or greater and the amperage reads 0-10 amps, refer to the starter solenoid and relay tests.
     

  8.  
  9. After the starting system problems have been corrected, verify the battery state of charge and charge the battery if necessary. Disconnect all of the testing equipment and connect the ignition coil cable or ignition coil connector. Start the vehicle several times to assure the problem was corrected.
  10.  

Before proceeding with this test, refer to the battery tests and starter feed circuit test. The following test will require a voltmeter, which is capable of accuracy to 0.1 volt.


CAUTION
The ignition system must be disabled to prevent engine start while performing the following tests.

  1. Disable the ignition system.
  2.  
  3. With all wiring harnesses and components (except for the coils) properly connected, perform the following:
    1. Connect the negative (-) lead of the voltmeter to the negative battery post, and the positive (+) lead to the negative (-) battery cable clamp. Rotate and hold the ignition switch in the START position. Observe the voltmeter. If the voltage is detected, correct the poor contact between the cable clamp and post.

    2.  
    3. Connect the positive (+) lead of the voltmeter to the positive battery post, and the negative (-) to the positive battery cable clamp. Rotate and hold the ignition switch key in the START position. Observe the voltmeter. If voltage is detected, correct the poor contact between the cable clamp and post.
    4.  
    5. Connect the negative lead of the voltmeter to the negative (-) battery terminal, and positive lead to the engine block near the battery cable attaching point. Rotate and hold the ignition switch in the START position. If the voltage reads above 0.2 volt, correct the poor contact at ground cable attaching point. If the voltage reading is still above 0.2 volt after correcting the poor contact, replace the negative ground cable with a new one.
    6.  

  4.  
  5. Remove the heater shield. Refer to removal and installation procedures to gain access to the starter motor and solenoid connections. Perform the following steps:
    1. Connect the positive (+) voltmeter lead to the starter motor housing and the negative (-) lead to the negative battery terminal. Hold the ignition switch key in the START position. If the voltage reads above 0.2 volt, correct the poor starter to engine ground.
    2.  
    3. Connect the positive (+) voltmeter lead to the positive battery terminal, and the negative lead to the battery cable terminal on the starter solenoid. Rotate and hold the ignition key in the START position. If the voltage reads above 0.2 volt, correct poor contact at the battery cable to the solenoid connection. If the reading is still above 0.2 volt after correcting the poor contacts, replace the positive battery cable with a new one.
    4.  
    5. If the resistance tests did not detect feed circuit failures, refer to the starter solenoid test.
    6.  

  6.  

Starter Solenoid
Bench Test
  1. Note the radio security code and the radio presets.
  2.  
  3. Disconnect the battery negative cable then the positive cable.
  4.  
  5. Remove the starter from the vehicle.
  6.  
  7. Disconnect the field coil wire from the field coil terminal.
  8.  
  9. Check for continuity between the solenoid terminal and field coil terminal with a continuity tester. Continuity (resistance) should be present.
  10.  
  11. Check for continuity between the solenoid terminal and solenoid housing. Continuity should be detected. If continuity is detected, the solenoid is good.
  12.  
  13. If continuity is not detected in either test, the solenoid has an open circuit, is defective, and must be replaced.
  14.  

On Vehicle Test
  1. Before testing, assure the parking brake is set, the transmission is in Park (automatic) or Neutral (manual), and the battery is fully charged and in good condition.
  2.  
  3. Connect a voltmeter from the (S) terminal on the solenoid to ground. Turn the ignition switch to the START position and test for battery voltage. If battery voltage is not found, inspect the ignition switch circuit. If battery voltage is found, proceed to next step.

  4.  
  5. Connect an ohmmeter between the battery negative post and the starter solenoid mounting late (manual) or the ground terminal (automatic). Turn the ignition switch to the START position. The ohmmeter should read zero (0). If not, repair the faulty ground.
  6.  
  7. If both tests are performed and the solenoid still does not energize, replace the solenoid.
  8.  

Starter/Ground Cable Test

When performing these tests, it is important that the voltmeter be connected to the terminals, not the cables themselves.

Before testing, assure that the ignition control module (if equipped) is disconnected, the parking brake is set, the transmission is in Park (automatic) or Neutral (manual), and the battery is fully charged and in good condition.

  1. Check voltage between the positive battery post and the center of the B + terminal on the starter solenoid stud.
  2.  
  3. Check voltage between the negative battery post and the engine block.
  4.  
  5. Disconnect the ignition coil wire from the distributor cap and connect a suitable jumper wire between the coil cable and a good body ground.
  6.  
  7. Have an assistant crank the engine and measure voltage again. Voltage drop should not exceed 0.5 volts.
  8.  
  9. If voltage drop is greater than 0.5 volts, clean metal surfaces. Apply a thick layer of silicone grease. Install a new cadmium plated bolt and star washer on the battery terminal and a new brass nut on the starter solenoid. Retest and replace cable not within specifications.
  10.  

Testing Preparation

NOTE
The air temperature should be between 59-100°F before any testing.

The starting system consists of an ignition switch, starter relay, neutral safety switch, wiring harness, battery, and a starter motor with an integral solenoid. These components form two separate circuits: a high amperage circuit that feeds the starter motor up to 300 or more amps, and a control circuit that operates on less than 20 amps.

Before commencing with the starting system diagnostics, verify:



The battery top posts and terminals are clean.
 
The alternator drive belt tension and condition is correct.
 
The battery state-of-charge is correct.
 
The battery cable connections at the starter and engine block are clean and free from corrosion.
 
The wiring harness connectors and terminals are clean and free from corrosion.
 
Proper circuit grounding.
