HARNESS AS-PANEL 4827514 - Caterpillar

the wire jumper and reconnect ECM connector J1/P1. Replace all wires. Expected Result:The voltage at the ECM is 24 3 VDC.Results:
OK - The voltage at the ECM is 24 3 VDC.Repair: The wire 382-RD and/or the connectors between the ECM and the ether start relay need repair. Inspect the wiring and connectors between the ether start relay and the connector at the ECM. Repair the connectors or wiring and/or replace the connectors or wiring.STOP
Not OK - The voltage at the ECM is not 24 3 VDC.Repair: Replace the ECM. Refer to the diagnostic procedure Troubleshooting, "Replacing the ECM".STOPTest Step 9. Check the Voltage from the Ether Hold Relay
Turn the engine control to the OFF/RESET mode.
Turn the battery disconnect switch to the OFF position.
Connect a voltmeter between the +Battery terminal of the ether hold relay and ground.
Turn the battery disconnect switch to the ON position.
Turn the engine control to the STOP mode.
Select the "Diagnostic Tests" on the Cat ET.
Select the "Override Parameters" screen on the Cat ET.
Activate the ether override and observe the voltmeter while ether injection is ON. Disable the ether override. Note: Do not allow the ether to be ON for more than two minutes. Damage to the solenoid may occur.
Measure the voltage at the ether hold relay.
Deactivate the ether override.
Turn the engine control to the OFF/RESET mode.
Turn the battery disconnect switch to the OFF position. Expected Result:The voltage is 24 3 VDC after the ether injection has been activated for two seconds.Results:
OK - The voltage is 24 3 VDC after the ether injection has been activated for two seconds. Proceed to Test Step 10.
Not OK - The voltage at terminal 30 is not 24 3 VDC after the ether injection has been activated for two seconds. Proceed to Test Step 12.Test Step 10. Check the Voltage at the Resistor and the Diode Assembly
Turn the engine control to the OFF/RESET mode.
Turn the battery disconnect switch to the OFF position.
Disconnect the connector for the resistor and diode assembly. Note: This procedure must be performed on all of the resistor and diode assemblies, if more than one resistor and diode assembly is present.
Connect a voltmeter to the +Battery pin of the resistor and the diode assembly and the engine ground.
Turn the battery disconnect switch to the ON position.
Turn the engine control to the OFF/RESET mode.
Select the "Diagnostic Tests" on the Cat ET.
Select the "Override Parameters" screen on the Cat ET.
Activate the ether override and observe the voltmeter while ether injection is ON. Disable the ether override. Note: Do not allow the ether to be ON for more than two minutes. Damage to the solenoid may occur.
Measure the voltage at the diode assembly and ground.
Deactivate the ether override.
Turn the engine control to the OFF/RESET mode.
Turn the battery disconnect switch to the OFF position. Expected Result:The voltage is 24 3 VDC.Results:
OK - The voltage is 24 3 VDC. Proceed to Test Step 11.
Not OK - The voltage is not 24 3 VDC.Repair:
