Information:
System Operation Description:The starting motor remains engaged after the engine has started.
Illustration 1 g00518564
Schematic For Starting Motor Relay (SMR) On "PEEC" Engines
Illustration 2 g00680589
Schematic For Starting Motor Relay (SMR) On "EUI" EnginesTest Step 1. CHECK THE SETPOINTS.This test step checks the following setpoints: P11 (crank terminate speed), P17 (total cycle crank time) and P18 (cycle crank time).
View the setpoints and make a note of setpoints P11, P17 and P18. See Systems Operation, "Engine/Generator Setpoint Viewing OP2".
Compare the setpoints with the specified setpoints of the particular generator set. The default value for P11 is 400 rpm. The default value for P17 is 90 seconds. The default value for P18 is 10 seconds.Note: Engines that are equipped with prelube pumps may require cycle crank times (setpoint P18) of 30 seconds or more. Expected Result:The setpoint value that is being viewed should match the specified setpoint value.Results:
OK - The setpoint is correct. Proceed to test step 2.
NOT OK - The setpoint that is being viewed does not agree with the specified setpoint. Repair: Reprogram setpoints P11, P17 and P18. See Systems Operation, "Engine/Generator Programming OP5-0". Stop.Test Step 2. CHECK THE START FUNCTION OF THE ENGINE.The following procedure will require checks to be made during simulated engine starting. Disable the fuel system.
Disable the fuel shutoff solenoid or the PEEC in order to prevent the engine from starting but not from cranking. To disable the EUI engine ECM, remove the J1-40 pin connector.
Prepare to manually stop the engine from cranking, if necessary. Turn the battery disconnect switch to the OFF position or shut the engine off by using mechanical means.
Turn the engine control switch (ECS) to the START position. Allow the engine to crank.
Turn the ECS to the OFF/RESET position.Expected Result:The engine should stop cranking.Results:
OK - The engine does not crank. Proceed to test step 6.
NOT OK - The engine continues to crank. Proceed to test step 3.Test Step 3. CHECK THE START FUNCTION OF THE ENGINE.
The conditions of the previous step remain. The fuel system is disabled. The engine is cranking.
While the engine is still cranking, push the emergency stop push button. Expected Result:The engine should stop cranking.Results:
YES - The engine does not crank. Repair: Check the wire on "RM-18" of the relay module for a short to +battery. Repair the short or replace the harness. If a short is not found, replace the relay module. See Testing And Adjusting, "Relay Module - Replace". Stop.
NO - The engine continues to crank. Proceed to test step 4.Test Step 4. CHECK THE START FUNCTION OF THE ENGINE.
The conditions of the previous step remain. The fuel system is disabled. The engine is cranking.
Stop the engine. Turn the battery disconnect switch to the OFF or shut the engine off by using mechanical means.
Remove all wires from TS1-25 in the generator housing. For dual starting motors, remove all wires from TS1-26.
Turn the ECS to START. Attempt to crank the engine.Expected Result:The engine should not crank.Results:
OK - The engine does not crank. Repair: The "SMS" or related wiring has failed.
