I have a 18RESA Kohler Generator that I keep getting a locked Rotor code warning. I clear it and then try to restart and it comes up again. The battery appears to be good.

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.

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

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.

The UV code has nothing to dow ith oil, poor oil would cause under frequency (low engine speed) Under voltage is caused by excessive load, short in the rotor/stator excition system, and/or AVR automatic voltage regulator. Of course loose wiring to will also cause it.

Check the oil pressure switch, and oil level first. Then check rotor brushes and rotor slip rings may need polishing. If the problem is still there check stator and rotor windings

I have a locked rotor fault message.


I had this fault show this morning. Very alarming, as we have a typhoon coming theough tomorrow!

Turned out to be an easy fix. When I hit start the solenoid engaged but nothing moved. Then I saw the fault message and thought "Large $$$$!"

It was just a bad 12 Volt battery, and when it couldn't crank it threw the fault code. I replaced the battery, pulled the 3 fuses on the control panel (mine is the 20 Kw model), and the codes cleared, and she fired right up.

The advice here and on a couple other sites about powering down the panel to clear fault codes saved me a lot of time, money and aggravaion, not to mention a freezer full of food (knowing the Guam Power Authority, and knowing typhoons, the power WILL go down tomorrow.

If it has a couple hundred hours or more, try cleaning the slips rings on the back of the rotor shaft. They should be very shiny and not black or polished looking.

You have to reset it because it locked out on on under frequency. Just pullout the fuse on the control panel and then reinstall it a couple of seconds later. Now it will reset the fault codes. Hope that helps.
