Hey Cafe,


Yes, I have the manual. Unfortunately, in the troubleshoting guide that lists the fault codes for OS it just says "Overspeed" Consult your Kohler dealer. Not much help.



I've been doing some googling and it appears that there is an OS sensor, but I can't find anything telling me where it is. I'm going to call the Kohler dealer tomorrow, they also do Yanmar and I buy all my parts from them. I'll let you know what they say.


I could be wrong, but I feel like it is a sensor that tripped because the charger went nuts and severely overloaded the genset. The OV code that popped up the first time I started it is also a clue, I think.
