Engine

Problem	Items to Check, Troubleshooting Steps, Remedies
Engine will not turn over	Possible causes: E-stop pressed. generator controller fault not cleared. Discharged or failed battery. Starter motor / solenoid failure. Electrical / wiring issue. Low voltage possible causes: One or both batteries failed (cell condition). Discharged batteries (drained, or not getting charged by the engine alternator). Poor connections, due to loose or corroded terminals. Intermittent or short circuit in the wiring Check the starter signal and ECM fuses in the 24 VDC distribution panel. (Position 16 & 9). Check the starter motor relay (Position 35). Replace or recharge the batteries or jump start / boost the batteries to start the engine (refer to Jump Start the VPS800A-T4).
Unsuccessful start attempts / Engine cranks but fails to start	If the generator controller has performed all three consecutive start attempts and has detected that the engine has not started, the ‘Fail to Start’ shutdown alarm message will be displayed. Possible causes: Low / no fuel level in tank Engine fuel system not primed Air leak into the fuel system Blocked intake air filter Cold temperature / grid heater Possible remedies: Check the ECM IGN / RUN fuse & relay in the 24VDC distribution panel. (Position 19 & 20). Prime the fuel system according to the engine manufacturer’s specifications. Check and ensure that all fuel line fittings are secured and that there are no fuel leaks near the fittings or the filters. NOTE Ensure that the gasket is installed on the fuel filters. Check air intake filter dust restrictor indicator Check air intake filter element Check grid heater solenoid Check grid heater fuse
Engine requires multiple cranking attempts before starting	Check that the fuel system is primed according to the engine manufacturer’s requirements. Check that all fuel lines, fittings and fuel filters are secure and that they do not allow air to enter the fuel system.

Engine will not turn over

Possible causes:

E-stop pressed.
generator controller fault not cleared.
Discharged or failed battery.
Starter motor / solenoid failure.
Electrical / wiring issue.

Low voltage possible causes:

One or both batteries failed (cell condition).
Discharged batteries (drained, or not getting charged by the engine alternator).
Poor connections, due to loose or corroded terminals.
Intermittent or short circuit in the wiring

Check the starter signal and ECM fuses in the 24 VDC distribution panel. (Position 16 & 9).

Check the starter motor relay (Position 35).

Replace or recharge the batteries or jump start / boost the batteries to start the engine (refer to Jump Start the VPS800A-T4).

Unsuccessful start attempts / Engine cranks but fails to start

If the generator controller has performed all three consecutive start attempts and has detected that the engine has not started, the ‘Fail to Start’ shutdown alarm message will be displayed.

Possible causes:

Low / no fuel level in tank
Engine fuel system not primed
Air leak into the fuel system
Blocked intake air filter
Cold temperature / grid heater

Possible remedies:

Check the ECM IGN / RUN fuse & relay in the 24VDC distribution panel. (Position 19 & 20).
Prime the fuel system according to the engine manufacturer’s specifications.
Check and ensure that all fuel line fittings are secured and that there are no fuel leaks near the fittings or the filters.

NOTE Ensure that the gasket is installed on the fuel filters.

Check air intake filter dust restrictor indicator
Check air intake filter element
Check grid heater solenoid
Check grid heater fuse

Engine requires multiple cranking attempts before starting

Check that the fuel system is primed according to the engine manufacturer’s requirements.

Check that all fuel lines, fittings and fuel filters are secure and that they do not allow air to enter the fuel system.
