Feed Circuit Test
Volt Ampere Tester:
The following procedure will require a suitable volt-ampere tester.
CAUTION: Before Performing any starter test, the Ignition and fuel Systems must be disabled.
Volt-Ampere Tester Connections:
1. Connect a volt-ampere tester to the remote battery terminals. Refer to the operating instructions provided with the tester being used.
2. To disable the ignition and fuel systems, disconnect the Automatic Shutdown Relay (ASD) in the Power Distribution Center (PDC). Refer to the PDC cover for the proper relay location.
3. Verify that:
- All lamps and accessories are OFF
- Automatic transmission shift selector is in PARK
- Manual transmission clutch pedal depressed
- Set parking brake
4. Rotate and hold the ignition switch in the START position. Observe the volt-ampere tester.
- Voltage above 9.6 volts, and amperage draw above 280 amps, check for engine seizing or faulty starter.
- Voltage above 12.4 volts and amperage reads 0 to 10 amps, check for corroded cables and/or bad connections.
- Voltage below 9.6 volts and amperage draw above 300 amps, the problem is the starter. Replace the starter refer to starter removal.
CAUTION: Do not overheat the starter motor or draw the battery voltage below 9.6 volts during cranking operations.
5. 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 ASD relay Start the vehicle several times to assure the problem has been corrected.
