Kohler generator drains battery while running and then shuts down with error code oc

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.

Maybe the start motor is damaged. You can check it first.

OC is Over Crank which generally means it cranked and cranked and failed to start. Turning the switch off and on again is the way to clear the fault. How long is it taking to start whilst cranking? It should start within 8 seconds

Check gas pressure. Oc is over crank. Means tried to start but did not.

Put it to run while holding the bullseye, you'll see the decimel move, wait for a number other than the run time to show and hit down, up, down, up, down, up then hit the bullseye until you see EC, it should should EC00, if not, select EC00 using up or down, then hit the bullseye until it says save and hit up and the bullseye again.

Its shutting down on over crank, which is a safety to protect the starter.

check your load wires there probaly reversed. I had the same problem friday. The week before the electrican wired it. did the same cc1 then oc. had a generator company come out it was the wireing. my load and netural were reversed.

U need to make sure that the relay driving ur auto start stay closed all thru the crank cycle.

Check battery volatge while you are cranking engine if voltage drops below 9 vdc you have a bad battery. If it doesn't you probable have a bad starting solenoid or a bad ground at the starting solenoid.

OC stands for Over Crank. How long does it take before the genset starts?
