Question about Kohler 14resa 14kw Home Emergency Backup Generator

Open Question

Kohler 14resa is the start up time delay changable

The generator comes on every week as scheduled. When it is tested by shutting off the power it comes on fine. But if the power goes off and then back on within 10 seconds or so, the generator starts to come on and go back off and shuts off on default. I go and restart and it goes to normal. It is the short flutter off/on for a few seconds that makes the unit disconnect and need resetting. I think the start time is 1 to 3 seconds after power failure. I am thinking the start time should be maybe 10 seconds

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.

SOURCE: kohler lp shuts down

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.

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.

SOURCE: Hello....i have several problems and

Hi and welcome to FixYa, I am Kelly.
I can not tell you how to get it out of it's current mounting position without seeing it. (Just being honest) And the wiring is different for each RV depending on what electrical system the ORIGINAL owner opted for. My experience with RV generator is that you can usually slide them out on rails just far enough to disconnect the wires. Just do yourself a HUGE favor and draw your own wiring diagram.
Number the wires 1 through 8 (
Ok.... here is the diagnostic and service manual:
http://www.kohlerpower.com/onlinecatalog/pdf/tp6196.pdf
See the troubleshooing steps on page 25 and also see sections 4-4 and 4-5 to determine why it is shutting down. First thing check the oil level! The engine has a Low Oil Level and low oil pressure Pressure Sensor. Either one will shut off fuel. Read in section 5 also....

The squalling noise your hearing is probably dry starter bearings. There is not a quick fix for this other than to disassemble the starter and lubricate it. If the bearings in fact dried out you will have to also wipe off the armature shaft area where the bearings are. If you just lubricate it without disassembly it will eventually lock up from the left over residue.

The fuel system is discussed on page 66 of the manual link. This appears to be an LPG powered unit. If it is not LPG powered find your engine number and I will get your engine service manual also so you can locate the fuel pump. (I think this is either the CH or CV740-0035 engine) If I remember correctly the fuel pump is vacuum powered on this engine if it a diesel or gas model. The diesel engine also has a fuel injection pump in addition to a fuel pump. (just depends on what sub model of the 12 RES-L you have. The L usually designates it as an LPG unit.)

14kw kohler propane generator-sometimes does not start, put battery jumper on and it starts. Battery is new, but had the same problem with the old battery.


The battery charger is defective, as you can start it by jumping it off means it is just a low battery. without it running measure battery voltage, it should be around 12V then plug the charger back in, it should climb to around 13.8B with a good battery. If not have the float charger checked.

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.

Although A bit inconvienent this does seem to be the norm for some Kohler units. Actually a small price to pay rather than having a technician come out to replace the ATS control board.

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.

Overcrank error message


The 'overcrank' error simply means it tried to start but never actually started. It cranked for an extended period. Check the fuel and starting issues you would normally check to start the engine.
