Diagnosis And Testing - Feed Circuit

The following procedure will require a suitable volt-ampere tester. See Fig 1.

1. Check battery before performing this test. Battery must be fully charged.
2. Connect a volt-ampere tester to the battery terminals. See Fig 2. Refer to the operating instructions provided with the tester being used.
3. To disable the ignition and fuel systems, disconnect the Automatic Shutdown (ASD) Relay. The ASD relay is located in the Power Distribution Center (PDC). Refer to the PDC cover for proper relay location.

4. Verify that all lights and accessories are OFF, and the transmission shift selector is in the PARK position or with the clutch pedal depressed and SET parking brake.
   CAUTION: Do not overheat the starter motor or draw the battery voltage below 9.6 volts during cranking operations.
5. Rotate and hold the ignition switch in the START position. Observe the volt-ampere tester. See Fig 1.
   • If voltage reads above 9.6 volts, and amperage draw reads above 280 amps, check for engine seizing or faulty starter.
   • If voltage reads 12.4 volts or greater and amperage reads 0 to 10 amps, check for corroded cables and/or bad connections.
   • If voltage is below 9.6 volts and amperage draw is above 300 amps, the problem is the starter. Replace the starter. See STARTER  under REMOVAL & INSTALLATION.
6. After the starting system problems have been corrected, verify the battery state-of-charge and charge battery if necessary. Disconnect all testing equipment and connect the ASD relay. Start the vehicle several times to assure the problem has been corrected.
