What brand of generator and KW? If you onlyone leg of the 22V it us not likely to be the voltage regulator aor rotor. Check to make sure that the voltage is checked right off the stator leads, where they feed the circuit breaker, and not on the load side of the circuit breaker, If you only have 120V on one of the 240V lines at that point, it is the stator winding.

I doubt its anything to do with brushes unless power system has shutdown incorporated, could ignition coil breaking down when it gets really hot or similar check the oil level cut out switch

On the inverter board itself. There should be a couple capacitors, a transformer and a resistor that make up the voltage regulator in the inverter board.

im not sure but easy to check remove tube from filter to carb and check visualy, wilst oppertating it

Your carburetor needle is stuck and gas is getting into the engine. You need to repair the carb and change the oil.

I had this same problem and solved it by replacing the AVR

try flipping the breaker or fuse this could be it or one of the wires came off the plug in or the plug went bad or the diod blew but all of these cane be fixed pretty easyjust need a meter to see what is bad good luck

First make sure you have fresh gas in the tank, as old gas can cause a 'no run' condition. Once you have fresh gas in the tank, make sure the gas flows freely all the way to the carb by removing the fuel hose from the carb inlet & checking for good flow (bad shut-off valve or obstructed hose by debris could cause same problem). Once you are sure that good, fresh gas is going into the carb w/o obstruction, remove the lower bowl from the carb - carefully - do not lose ANY parts, starting with the washer on the bolt. With fuel flow 'ON', fuel should flow freely when this bowl is removed, so shut off fuel valve in the hose. Now, if you carefully remove the bolt / brass tube from the center of this bowl area (center of plastic float) - remove bolt downward, like you would a lightbulb from the ceiling - this bolt should have several holes in the side, they are probably clogged, so unclog them with a needle or wire, wipe clean, and reinstall. That probably just solved all your problem.... if not, you likely will want to replace the carb completely, as it is not very expensive, and will surely solve your problem. *** Be careful with gas fumes !!! ***

Try replacing the capacitor. You can buy it from http://www.jackssmallengines.com/do_it_home.html. When you pull off the power end of the generator look at the diodes also. If they look toasted replace them as well

10-30W or a SAE30. usualy 600mls 0r 1200mls

I had a Colman that only surged when it had a large load on it. ConsumerReports.org says that some Coleman generators just can't hold a constant voltage. Hondas are expensive but very good,.
