(1) If the accelerator pedal is lifted quickly, the engine will not continue to rise after reaching the maximum speed, and the accelerator pedal or the arm will be stuck.

(2) If the accelerator pedal is lifted quickly, the engine speed cannot be reduced or immediately extinguished, usually the governor is faulty.
(3) If the engine speed continues to rise after picking up the accelerator pedal, the fuel pump is faulty.

(4) If the oil supply system is good, there is extra fuel or oil in the cylinder.

Honneywell 11kw generator with error codes 1600 and 1603 how to fix it and get it working

According to page 64-65 of the 350 !! page manual in this link -
"1600" says you have overloaded the generator.
"1603" says it only applies to 8kw models and the generator is overloaded.
I'm guessing from the limited info you gave that this is an Evolution generator.
See if reducing your load makes the error disappear even if you don't have the Evolution model.

Check voltage on sensor wires during cranking, it shoupld be approx 2V AC. If not replace sensor.

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

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.

I have a generac 22kw model QT02224anan that will run for a few minutes then shut down , then the over speed led is lit. It only happens when it is under load or during a power outage. it goes through...

its possible the overspeed is set to sensitive. or your rpm are to high. these are preset in the factory as a safety, check your manual to ensure your rpm speed is in the pre set area. generators will do this under load when you have a big load on them or take a load off. the governor will some times over compensate causing it to trip on overspeed.

10kw Generac shut down overspeed

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.

Engine overspeed light blinking

Hi there,
You probably have a broken magnetic pickup.
You'll have to reset the generator controller, usually this is just a matter of turning the switch of the off position. On most of the generators I've worked on a blinking overspeed light as opposed to a solid one means that the control board can't detect any speed input. Speed input can be either a wire that comes from the generator output, or a magnetic pickup mounted so that it can count flywheel teeth. You don't say which generator this is so I can't guess any better than that.
