Typical exampleTest Step 1. Check for Connector Damage.
Turn the circuit breaker CB-8 to the OFF position.
Turn the main disconnect switch to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and pinch points.Expected Result:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - The connectors and wiring are okay. Proceed to test step 2.
Not OK - The connectors and/or wiring are not okay.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 2. Monitor the Parameter for the Start/Run/Stop Switch on the Caterpillar Electronic Technician (ET).
Start the Cat ET.
Turn the circuit breaker CB-8 to the ON position.
Turn the main disconnect switch to the ON position.
Turn the "Master Power" switch to the ON position.
Turn the "Gear Selector" knob to the NEUTRAL position.
Monitor the parameter for the Start/Run/Stop switch on Cat ET.
Turn the "Deck Start/Run/Kill" switch to the START position.Expected Result:The parameter for the Start/Run/Stop switch should read "ON".Results:
OK - The parameter for the Start/Run/Stop switch does read "ON".Repair: The "Deck Start/Run/Kill" switch circuit is operating properly. Check for diagnostic codes. Stop.
Not OK - The parameter for the Start/Run/Stop switch does not read "ON". Proceed to test step 3.Test Step 3. Check the Voltage from the "Deck Start/Run/Kill" Switch.
Connect a voltmeter between terminal 10 in the main junction box and engine ground.
Turn the "Deck Start/Run/Kill" switch to the START position.
Monitor the voltage on the voltmeter.
Turn the "Deck Start/Run/Kill" switch to the RUN position.
Monitor the voltage on the voltmeter.
Turn the "Deck Start/Run/Kill" switch to the "KILL" position.Expected Result:The voltage should measure
