Question about Kohler 14resa 14kw Home Emergency Backup Generator

1 Answer

I have a locked rotor fault message.

The generator will not start and the display reads locked rotor. What should I be checking? Have already checked the battery and connections.

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.

    By the way, the battery showed 14.1 volts, but apparently lacked the amperage to crank that big boy.

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.

When a generator is heating after a few minutes what could be the cause


not enough information to answer. gas or propane?. if new,generator by it's very nature generates energy,and thereby heat. even coiled wires can get warm. what part is hot?
if you've owned it a while, and it is inordinately hot as compared to prior uses, is it lubricated ? running normal otherwise?

What is the wattage draw for an AIR V unit, my 4000/3500 generator seems to load out and will not start the compressor !


A generator must be able to put out the locked rotor amps listed on unit in order for it to start . Locked rotor is usually 4 to 5 times the normal run amps .

My 3kva generator not show voltage.I already change carbon bushes and AVR too.but result is still zero.please help me.


You need to measure the rotor and stator for correct resistance and shorts. You will need a good ohm meter and teh exact readings mostly on a rotor approx 22ohm and stator can be less than 1 ohm, but zero ohms to ground on any lead or ring

GE Generator 10kw model #040448. TRANSFER SWITCH FAULT message being displayed. Generator works fine. Generator output load voltage = 233V.


This generator has a built in transfer switch. If you do not have an external source of 240 volts going in to the unit (utility power), the transfer switch will show a fault or "abnormal" reading. If you do have utility power going in to the transfer switch, and the generator is on then you have a faulty transfer switch. It is time to warranty or get a replacement switch.

Rotor won't turn due to rare earth magnets have to much magnetism. The generator was working fine and the bearings had to be replaced. After replacing bearings and reassembling the generator we were...


You do not say what type/model generator you have, so I will just give you some basics.

There is nothing wrong with the magnets. Their power did not change at all, their pwer never changes, except to degrade slightly over time (hundreds of years.)


The generator rotor is hitting the stator. In other words, the alignment of the rotor inside the generator is off center, making the rotor bind on the inside of the stator, resulting in a lock-up.

With the generator attached to the motor, remove the generator end, and slowly try to turn the engine over by hand. REMOVE THE PLUG WIRE FROM THE PLUG FIRST, so that the engine cannot start. Watch inside the generator, and discover why the generator rotor is not aligned. Pehaps the bearings were installed incorrectly, or the housing is installed incorrectly. Most generator engines have a tapered power-takeoff shaft, where the gen. shaft connects to it. Is this Bolt tightened to specifications? Is there some debris floating around in the gen. (such as a screw, or a pebble, or a nut) that would impede its movement?

good luck

forget about the display read the manual and find out how many volts are needed to charge the battery....then
get a voltometer and disconnect the terminals from the battery and connect them to the voltometer while the generator is running...
find out what the reading is...if the reading is zero (0)...then post a problem on (no out put)...
if not.....then there has to be a mistake...
if it reads a voltage thats too low..then you AVR card is burnt out (AVR card is located in the other end of the generator (beyond the stator-side cover)...

You have a brushless generator and you've already checked the capacitor that does the voltage regulation (wiring is fine).
The next thing to look at are the diodes, movs, and wires in the rotor.
