KIT-VALVE 3082888 - Caterpillar

Activate the ether override and observe the voltmeter while ether injection is activated. Disable the ether override.Expected Result:The voltage is 24 3 VDC.Results:
OK - The voltage measured 24 3 VDC. Proceed to Test Step 11.
Not OK - The voltage did not measure 24 3 VDC.Repair: There is a problem in the harness between the ether hold relay and the resistor and diode assembly. Repair the connectors or wiring and/or replace the connectors or wiring. Verify that the system is operating correctly. Replace the ether canister on the ether solenoid.STOPTest Step 11. Check the Resistor and the Diode Assembly
Disconnect the connector at the resistor and the diode assembly.
Set the multimeter to the "Check Diode" setting.
Connect the positive lead of the multimeter to terminal 2 and the negative lead to terminal 1 of the resistor and the diode assembly and observe the multimeter.
Connect the positive lead of the multimeter to terminal 1 and the negative lead to terminal 2 of the resistor and the diode assembly and observe the multimeter.
Repeat the measurements for all of the resistor and the diode assemblies if more than one resistor and diode assembly is present.Expected Result:When the positive lead of the multimeter is connected to terminal 2 and the negative lead to terminal 1, the multimeter displays an overload "(OL)" condition.When the positive lead of the multimeter is connected to terminal 1 and the negative lead to terminal 2, the multimeter displays a number less than one.Results:
OK - The resistor and the diode assembly is operating correctly.Repair: There is a problem in the harness between the resistor and diode assembly and the ether solenoids. Repair the connectors or wiring and/or replace the connectors or wiring. Verify that the system is operating correctly. Replace the ether canister on the ether solenoid.STOP
Not OK - The resistor and the diode assembly is not operating correctly.Repair: The resistor and the diode assembly is causing the problem. Replace the resistor and the diode assembly. Verify that the system is operating correctly. Replace the ether canister on the ether solenoid.STOPTest Step 12. Check the Battery Voltage to the Ether Hold Relay
Measure the voltage between wire 147-PU on terminal 30 of the ether hold relay and ground.
Measure the voltage between wire 147-PU on terminal 86 of the ether hold relay and ground.Expected Result:The voltage measures 24 3 VDC.Results:
OK - The voltage measures 24 3 VDC. Proceed to Test Step 13.
Not OK - The voltage did not measure 24 3 VDC.Repair: Verify that the breaker for the starting aid is not tripped. Verify that the main power relay and the alternator are operating correctly. Disconnect wire 147-PU on terminal 30 of the ether hold relay. Check wire 147-PU for continuity to the alternator. If the wire is not OK, repair the wire. Verify that the system is operating correctly. Replace the ether canister on the ether solenoid.STOPTest Step 13. Check the Coil of the Ether Hold Relay
Turn the keyswitch to the OFF position.
Remove wire F707-WH from
