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.

My 18RESL Kohler Propane Generator ran for 8.5 hours and shut down for overspeed. later it started up again and shut down for under frequency. Now it won't even turn over. Where do I start. I checked...


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.

Code UU


Here is the code explained direct from Kohler's manual. I'd disconnect the generator load first.
UU Undervoltage Shutdown occurs if the voltage falls below 80% of the nominal system voltage for more than seconds. Check wiring and connections.
Reduce the load and restart the generator set. —
Check wiring and Check controller configuration, system voltage
and frequency (parameter UU).

Check AC voltage and adjust, if necessary. 5.7
Replace the SCR module and test voltage again. 4.9
Separately excite unit. 5.2
Check stator continuity

Could be the battery voltage. If your battery is not charging properly, the controller on the unit can do some funky things! Exactly how long does it run for? Is this in auto or manual mode?

Kohler 12kw generator starts but shuts down after 3sec


Your gas pressure is too low and you may not have a large enough supply pipe. You need at least 10 inches of water column with the engine running to operate an LP vapor fueled engine. Because the engine is starving for fuel, its governor opens the throttle to WOT (so it goes to high revs) but there isn't any fuel to make horsepower with so the output voltage falls and the undervoltage alarm trips.
