My mule has had 3 regulators and runs ok when battery is low. when its full the engine cuts out when increasing revs above idle. i'm sure its overcharging. when running the coils are recieviving 18 to 19 volts!!! ive fitted genuine kawasaki regulators. i had to remove the buzzer that used to sound every time it was cutting out.
Bad ground be my guess loose wire ?
SOURCE: Engine cut out under revs but will idle
fueling problem. its not getting enought fuel from the carb. check the pipes, jets and floats.

Running well at high revs would indicate that all the fuel and air it needs are getting to the engine and you also have a good spark. Probably no problem with air and fuel filter ( if fitted) or sparkplugs.
Running hot, and bad idling are signs of a lean air fuel mixture. The engine is probably not getting enough fuel at low revs.
This could be caused by an air leak between the carburettors and the engine. Check that the vacuum line to the fuel tap is properly secured at both ends. It is behind the fuel line at the tap.
Get a a short length of hollow plastic tube and use it like a stethascope - put one end to your ear and move the other end around your carburettor mounts with your engine revs as low as you can get, and listen for any sucking noises that would indicate a leak. Look for cracks in the rubber inlets.
The other possibility is that there is an internal blockage in the idling jets or idling fuel circuit. This is where dirt tends to lodge because the jet dimensions and passageways are very fine - The high speed jets are much bigger and dirt often just passes straight through.
Try a little bit of choke while the engine is warm to see if you get a stronger low speed response. If so that would point to an internal blockage.

voltage reg. may be bad.19 Volt DC will destroy other electrical, dont run it and risk it.

This could be due to timing screw being incorrectly set
Locate gold timing screw on the carbrettta turn it clockwise
only slightly till bike idles without choke on, Then when choke it on it should idle a touch higher.
SOURCE: charging system is overcharging the
rectifier (voltage regulator) is responsable for stady 14V suply.
It should be him. Check battery when not conected?!
But I realy think it's rectifier cousing problem!
