Make sure that the throttle linkage is all there and not damaged/misadjusted, then get a manometer and check your inlet gas pressure. Gas pressure should be 8 inches of water column and stay there running or not.

Check the vent in the fuel cap to make sure its free to breath. It could be creating a vaccume in there and starveing for fuel. Maybe run it with the gas cap off and see if the problem gos away.

SOURCE: Attempted to start Generac Guardian 15 kw air

I work on these every day. Its either gonna be the rotor or stater, the voltage regulator, but most likely its a bad stepper motor which is the throttle motor, or control board. Thats all that could be causing that so its one of those. If its the rotor or stater thats bad it causes the generator to RPM up because it thinks its not producing enough power due to that. I had the same problem with the same one we just fixed and it was the slip rings on the end of the rotor so bad rotor.

SOURCE: 5500 generator stopped producing eletric after

First check with the dealer and see if it is still under warranty. If it is not, make sure nothing is blocking the air flow around where the control modules are located. This could cause the voltage regulator and other electronic parts to overheat. Next check the brushes and make sure they are free of any dust or build up preventing them from making contact.

If everything is OK the next thing I would do is change the voltage regulator.

What is the general specification of Genset 20kv?


Generally 20 Kva power generator can produce more power. The voltage used in this 20 kva generator is 3 phase with frequency 50 Hz. 20 kva generator engine is already very enough for use on buildings that require large electrical power or public places such as shops. According to me HARGEN provides the best high quality genset.
To fill the fuel tank to the full required 62 liters of fuel in order to use this 20 kva generator engine with more leverage.
20 kva generator engine is also issued a noise that can reach 61.7 db or can be heard up to a distance of 7 meters away from where this generator is located.

How to fix over speed fault in desiel generator?


On the flywheel is a small sensor you should see it, like a threaded bolt with wires, that goes into the housing. This is the mag pickup speed sensor, it can get metal filings on it causing this fault. Unscrew it and wipe it off, screw it CAREFULLY all the way down with your fingers until it touches the flywheel then back out one turn, it is a small gap. Crank engine and measure the voltage on the sensor wires will be approx 2 VAC if it is working, if not replace sensor

Generac Guardian 12 KW Model 04456-2 shuts down on overspeed in cold weather


Leigh,
See my 5/22/12 comments on my "overspeed fault" problem resolution [Generac 43903 standby Generator overspeed indicator on starting] . If it only runs for a few seconds and then quits, you may have a similar condition to the one my unit had. A good technician should be able to diagnose the problem and determine if you have a similar failure to the one I had, or one of the other causes suggested by RSG000.

Check the genset controller for a fault, low oil psi, no output voltage, overspeed, overcrank / no crank disconnect signal / starter staying engaged, high engine temp.
