Starter Feed Circuit Resistance

Print

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 and fuel systems must be disabled to prevent engine start while performing the tests.

  1. Disable the ignition and fuel systems by disconnecting the Automatic Shutdown (ASD) relay, located in the Power Distribution Center (PDC) in the engine compartment.
  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.

    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.

  5. Remove the heat 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.

    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.
