Check for a plugged fuel filter. Refer to the Engine Service Manual.
Check for a plugged air filter. Refer to the Engine Service Manual.Expected Result:The air and fuel systems are within specifications.Results:
OK - The air and fuel systems are within specifications. Proceed to Test Step 3.
NOT OK - One or more of the items in this Test Step are NOT within specifications.Repair: Correct the problem with the corresponding system. Reset the genset. Operate the genset and verify that the problem has been corrected. Stop.Test Step 3. CHECK THE FUEL SYSTEM
Check the fuel system. In order to check the fuel control solenoid, see Testing And Adjusting, "CID 566 FMI 7 Unexpected Shutdown Improper Mechanical Response - Test". Check for a fault with the engine starting system or the fuel system.Expected Result:There is no fault.Results:
OK - There is no fault in the engine starting system or the fuel system. Proceed to Test Step 4.
NOT OK - There is a fault in the engine starting system or the fuel system.Repair: Exit this procedure. Troubleshoot the indicated fault. Refer to the Engine Service Manual. Stop.Test Step 4. CHECK THE FUSES.
Check the fuses "F2" and "F4" on the relay module.Expected Result:The fuse is NOT blown.Results:
OK - The fuse is NOT blown. Proceed to Test Step 5.
NOT OK - The fuse is blown. Proceed to Test Step 13.Test Step 5. CHECK THE SETPOINTS.
View the setpoints P017 and P018. Make a note of the setpoints. See System Operation, "Engine/Generator Setpoint Viewing OP2-0". Compare the setpoints against the default setpoints of the particular generator set.Note: The factory default values are 90 seconds for P017 and 10 seconds for P018. Engines that are equipped with a prelube pump may require a cycle crank time (setpoint P018) of 30 seconds or more.Expected Result:The setpoints are correct.Results:
OK - The setpoints are correct. Proceed to Test Step 6.
NOT OK - The setpoints are NOT correct. Repair: Reprogram the setpoints. Reset the genset. Operate the genset and verify that the problem has been corrected. Stop.Test Step 6. CHECK THE BATTERY VOLTAGE.
The engine should be off.
Measure the system voltage at the battery.Expected Result:For 24 volt systems, the voltage should be from 24.8 to 29.5 DCV. For 32 volt systems, the voltage should be from 33.1 to 39.3 DCV.Results:
OK - The voltage is correct. Proceed to Test Step 7.
NOT OK - The battery voltage is NOT within specifications.Repair: Further testing of the battery system is necessary. See Special Instruction, REHS0354, "Charging System Troubleshooting". Stop.Test Step 7. CHECK THE ENGINE STARTING FUNCTION.Note: The GSC+ is attempting to crank whenever the K4 indicator is ON. The K4 indicator is located on the lower display. Be aware of the 10 second crank cycle (set by P018) that is factory set. Be sure that the K4 indicator is ON while you are making the following measurements. More than one start may be required
