Step 6. Check the Alternator
Test the alternator for correct operation. Refer to Systems Operation, Testing and Adjusting, "Alternator - Test".Results:
The alternator is faulty. - Repair: Replace the alternator.Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.STOP
The alternator is operating correctly. - Proceed to Test Step 7.Test Step 7. Check the Batteries
Load-test the batteries. Use a suitable battery load tester. Refer to Systems Operation, Testing and Adjusting, "Battery - Test" for the correct procedure.Results:
The batteries pass the load test. The measured voltage is at least 11.0 VDC. - Proceed to Test Step 8.
The batteries do not pass the load test. The measured voltage is less than 11.0 VDC - Repair: Recharge or replace the faulty batteries.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair eliminates the fault.STOPTest Step 8. Check the Ground Wire and the Battery Disconnect Switch
Disconnect the battery negative terminal.
Ensure that the battery disconnect switch is in the CLOSED position.
Use a suitable multimeter to measure the resistance between the battery negative terminal on the harness connector and both of the terminals on the battery disconnect switch.Expected Result:Each resistance measurement should be less than 5 Ohms.Results:
OK - Both resistance measurements are less than 5 Ohms. Proceed to Test Step 9.
Only one of the resistance measurements is less than 5 Ohms. - The fault is in the battery disconnect switch.Repair: Replace the battery disconnect switch.Reconnect all wires and verify that the repair eliminates the fault.STOP
Both resistance measurements are greater than 5 Ohms. - The fault is in the wiring between the battery negative terminal and the battery disconnect switch.Repair: Replace the faulty wiring.Reconnect all wires and verify that the repair eliminates the fault.STOPTest Step 9. Check the Ground Wire Between the Battery and the ECM
Disconnect the battery negative terminal.
Ensure that the battery disconnect switch is in the CLOSED position.
Use a suitable multimeter to measure the resistance between the battery negative terminal on the harness connector and the following terminals:
P1:2
P1:4
P1:6Expected Result:Each resistance measurement should be less than 5 Ohms.Results:
OK - Each resistance measurement is less than 5 Ohms. Proceed to Test Step 10.
Not OK - At least one of the resistance measurements is greater than 5 Ohms. The fault is in the wiring between the battery disconnect switch and the P1 connector.Repair: Replace the faulty wiring.Reconnect all wires and verify that the repair eliminates the fault.STOPTest Step 10. Check the Keyswitch Signal Voltage
Turn the keyswitch to the OFF position.
Disconnect the P1 connector from the ECM.
Turn the keyswitch to the ON position. Do not attempt to start the engine.
Measure the voltage between P1:54 and a suitable ground.
Turn the keyswitch to the OFF position.Results:
The measured voltage is at least 11 VDC - The keyswitch signal is reaching the ECM. Reconnect the P1 connector and proceed to Test Step 11.
The measured voltage is less than 11 VDC - Repair: The keyswitch signal is not reaching the ECM from the machine main relay.Refer to
