Information:
OK - The connectors and/or wiring need repair.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 2. Check the Voltage at the Battery Post.
Turn the circuit breaker for the engine to the ON position.
Turn the keyswitch to the ON position. The engine should be off.
Measure the voltage at the battery posts.Expected Result:The voltage should be 24 3 VDC.Results:
OK - The voltage is 24 3 VDC. Proceed to test step 3.
Not OK - The voltage is not 24 3 VDC.Repair: There is a problem with the batteries or the charging system. Refer to Testing and Adjusting, "Charging System". Stop.Test Step 3. Check the Voltage to the ECM.
Turn the keyswitch to the OFF position. The engine should be off.
Turn the circuit breaker for the engine to the OFF position.
Remove ECM connector J1/P1.
Turn the circuit breaker for the engine to the ON position.
Turn the keyswitch to the ON position. The engine should be off.
Measure the voltage between P1-4 and P1-11 at the ECM connector P1.
Measure the voltage between P1-6 and P1-5 at the ECM connector P1.Expected Result:The voltage should be 1 VDC from the voltage at the battery terminals.Results:
OK - The voltage should be 1 VDC from the voltage at the battery terminals. The voltage at the ECM is okay. Proceed to test step 4.
Not OK - The voltage should be 1 VDC from the voltage at the battery terminals. The voltage is not correct at the ECM.Repair: There is an open circuit or excessive resistance in the wiring or connections between the batteries and the ECM. Verify that the breaker for the Engine is not tripped. Verify that the Main breaker is not tripped. Verify that the connection for the engine ground is clean and tight. Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 4. Check the Voltage at the Input for the Keyswitch at the ECM.
Measure the voltage between wire 113-OR from ECM connector P1-23 and wire 229-BK from ECM connector P1-11.
Turn the keyswitch to the OFF position. The engine should be off.
Turn the circuit breaker for the engine to the OFF position.
Reconnect all wires and connectors.Expected Result:The voltage should be 24 3 VDC.Results:
OK - The voltage is 24 3 VDC. Proceed to test step 7.
Not OK - The voltage is not 24 3 VDC. Proceed to test step 5.Test Step 5. Check the Voltage at the Keyswitch.
Turn the circuit breaker for the engine to the ON position.
Turn the keyswitch to the ON position. The engine should be off.
Measure the voltage between terminal R and engine ground at the keyswitch.
Turn the keyswitch to the OFF position. The engine should be off.Expected Result:The voltage should measure 24 3 VDC.Results:
OK - The voltage measures 24 3 VDC. Proceed to test step 6.
Not OK - The voltage does not measure 24 3 VDC.Repair: Check for 24 3 VDC at
