    I have a 11rmy LP, it will start and run from 5 seconds up to 1 minute. I changed the regulator, electronic governor, diodes, filters and plugs. This unit is 9 years with only 150 hrs.

    No matter what you shouldn't hold the governor arm or the throttle to prevent the governor from working, you could do serious damage to the engine in a very short time. I'm not as familiar with your generator as I am others, can you tell me if you have and electronic governor or a mechanical one? Also am I correct in thinking that this is an LP fueled generator? If you've got LP fuel you could very easily be having issues related to fuel pressure and/or delivery volume - this is especially true in cold places :-)

    Hope this helps,
    Carl

What you need to know is there enough fuel going to the regulator. It should be 7 to 11 inches Water Column. If not your problem may be not enough fuel. That includes when the heater in your house kicks on and what ever gas appliance you may have. Once you verify that you need to figure out if you have the proper pressure coming out of the regular on the inside of the generator. Next I would look at compression of the cylinders. It may need new piston rings.

change the oil to the correct specification first. As the engine runs the heat changes the viscosity and overheats or trips the oil alert switch. If its over 10 years old change the oil alet magnetic switch

Kohler Model 12RES LP gas generator starts normally but immediately shuts down with over-voltage alarm. Control panel replaced.


Sounds like a short in one of the windings to me. Can you verify that the engine rpm is not exceeding specs? If you can modify the engine speed Id say slow it down and see what the voltage read is.

My Kohler 17RES has stopped doing it's scheduled weekly exercise. How can I get it exercising again?


On your Automatic Transfer Switch ( the little gray box you see on the right in the picture above) you have two blue buttons. One is a Manual test switch. The other has a clock on it and this is your exercise set button. Hold it down for a FULL 3 seconds if you want it to excercise without a load (not powering your home) Hold it down for a FULL 6 seconds if you want it to exercise with a load every week. Your generator will start and run for 20 minutes, and then shut down. Now every week your generator will exercise at the time and day that you pushed the set button.
