OC means OVERCRANK safety circuit stopped the auto start-up so you wouldn't burn up the starter. There is a reason the generator didn't start. Low battery, not enough fuel pressure, clogged air filter, bad starter... You just have to eliminate as many as you can visually. Rebooting the generator should clear the OC condition and you can try to start it manually.

Kohler 12.5 res gen. Battery is good. Get OC code. If I reset auto switch by clicking off, then clicking run, then clicking auto it will start. Any thoughts on this issue?


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

The generator has stoped working after runing about 9 hours


Check what fault was logged on the controller and address the fault from there. Also note that the generator will not operate automatically at all if it is out on a fault until the problem is addressed and the unit is reset and put back in automatic. On the 18 open the top cover and the fault should show up as a 2 digit abbreviation and the definition will be defined just below it on the sticker.Such as OC is overcrank which means it tried to started but failed possibly due to lack of fuel or LOP is low oil psi, usually means it burned all the oil out of the crankcase.
