HOSE AS 2390021 - Caterpillar

Do not allow the ether injection system to be on for more than two minutes. Damage to the ether solenoid may occur.
Activate the ether override and observe the voltmeter while ether injection is activated.
Disable the ether override.
Reconnect all connectors. Expected Result:The voltage at the ether solenoids is 24 3 VDC during the first two seconds of injection. The voltage at the ether solenoids decreases to 5 3 VDC after the first two seconds of injection.Results:
OK - The voltage is approximately 24 3 VDC for the first two seconds of injection. The voltage then decreases to 5 3 VDC for the remainder of injection.Repair: If ether is not being injected, replace the ether solenoids. Verify that the system is operating correctly.STOP
Not OK - 24 VDC - The voltage did not measure 24 3 VDC for the first two seconds of injection. Verify that wire 200-BK(Black) has continuity to ground. If wire 200-BK(Black) has continuity to ground, proceed to test step 9.
Not OK - 3 VDC - The voltage is approximately 24 3 VDC for the first two seconds of injection. The voltage did not decrease to 5 3 VDC for the remainder of the injection duration. Proceed to test step 9.Test Step 9. Check the Battery Voltage to the Ether Start Relay and to the Ether Hold Relay
Disconnect the connector for the ether start relay and the connector for the ether hold relay.
Measure the voltage between terminal
