Locked Rotor is reported as an overcrank fault "OC".

You first need to verify the engine fails to crank, which is likely a starter motor or start circuit failure.

If the engine cranks three separate times and then the OC fault occurs, it simply means the engine did not run... more likely a fuel issue.

But either can be caused by numerous reasons.

Kohler 18RESL ... | Answered on Jan 06, 2020


My 11 month old Kohler 14RESL stopped working sometime this month. The GFI outlet to the trickle battery charger tripped and the battery charger went dead and so did the battery. When I realized the GFI had tripped, I reset it and the trickle battery charger started recharging the battery overnight. In the morning I tried to start the generator by pushing the run button - nothing happened except a message 'noEc' appeared on the status screen. I called Kohler and was referred to their local distributors. After a whole day of phone calls to many distributors, I finally found one, Kraft Power, who would come out on an overtime basis and fix the problem. I chose Kraft Power because they were the only company who knew what 'noEc' meant. They told me that since the generator had lost all power (no trickle battery charger), the engine had lost it's configuration! I have worked in the technical field for 25 years (computers, networks and remote diagnosis) so this answer was particularly troubling. THIS SHOULD NOT HAPPEN. The technician had to connect to the port on the controller, bring up Site Tech on his laptop, and enter two pieces of of information into the configuration. 1) 14RESL and 2) the engine type. We had to use a mirror to read the engine type as it was under the oil filter!

Kohler 12 kW... | Answered on Jan 04, 2020


It definately sounds like a fuel problem, lack of fuel..I assume it is running on LP or natural gas. The hose running from the demand regulator goes to the carburetor/mixer. When it gets to the carburetor, there is an adjustable main jet. It is different on different models, but is usually easy to find. There is probably a screw slot in the end of the screw head and a spring under the head. Start it up after locating the screw and open the jet just enough to even out the running. It was factory set, but barometric pressure and altitude and different fuels in different areas will decessitate different settings.
Please let me know if this fixes your problem, Robert

Six steps of start-up Shangchai generator set :
A.Unscrew the deflation screw on the fuel injection pump, use the fuel hand pump to remove the air in the fuel system, and fix the adjusting control handle on the throttle position of the suitable starting speed;
B.Pressthe generatorstart button to start the diesel engine. If the diesel engine can't start in 10 seconds (up to 15 seconds), it should wait for 1 minute before starting for the second time. If it can't start for three consecutive times, should check and find out the cause of the failure;
C.After diesel generator set start up, the no-load speed gradually increases to 1000-1200 r/min (note not to run at low speed for a long time). After the diesel engine is preheated, the speed is increased to the rated speed. When the outlet water temperature reaches 55 degrees Celsius and the oil temperature reaches 45 degrees Celsius, full load operation is allowed;
D.After starting the diesel engine, pay close attention to the reading of oil pressure gauge (2.5-3.5kg/C?in normal operation). If the oil pressure gauge does not indicate, stop immediately and check whether the ammeter has charge indication;

E.After the diesel generator set is put into normal operation, should observe the changes of water temperature, oil temperature and oil pressure at any time, and should handle the reading of power meter, frequency meter, ammeter and voltmeter in time if abnormalities are found;
F.When each instrument of the genset indicates normally, can turn on the load switch to send power to the load. With the change of load of the genset, if the frequency and voltage are not within the prescribed range, should adjust the frequency and voltage in time to maintain the rated value. It is strictly prohibited that the genset carry load at low speed, so as to avoid damage to the equipment.

Emergency shutdown operation is required when one of the above conditions occurs in diesel generator set.Diesel generating set itself has an emergency stop button, at this time, press the emergency stop button or quickly press the stop control handle of fuel injection pump to the stop position, the diesel generator will quickly cut off the load, and immediately close the throttle, while the red "emergency stop" light is on. Need to press the button again to delete the emergency stop signal. If there are serious faults or distribution faults, you can also press the button on the control panel, and the unit will stop immediately.

In fact, all faults always give operators some warning signal before spare parts break down or engine damage occurs. So the operators need to be smart, and notice alarm signals (sudden drop in oil pressure, abnormal sound, etc.) and immediately stopping the engine.
Emergency shutdown operation is different from normal shutdown operation.
Emergency shutdown operation.Once the operator finds that there is a serious fault or distribution fault in thediesel generating set, he can press the emergency stop button of the control panel to stop the unit immediately. If there is no special circumstances, we advise users not to stop the unit at will through the emergency stop button.

Can you be more specific? what model Kohler is it, Model number KW etc.

Kohler... | Answered on Aug 30, 2019


I think you can ask your supplier, they most know their generator.
If you plan to have a new diesel generator set, maybe you can consider Cummins, Volvo, Perkins, as well as China made generator: Yuchai, Shangchai, Weichai, Ricardo etc.

The engine is failing to run after a commanded start. Repeatedly.

Kohler... | Answered on Apr 19, 2019


Are there any faults listed on the control display? If display is dark then likely a battery issue. Check battery voltage with a Digital Multi Meter (DMM). It should be at least 12.5VDC.
