30REOZJC Kohler generator surges. Displays Frequency High Shutdown

SOURCE: Coleman generator OHV3000

The carburetor is probably clogged up. Mix a bottle of carburetor cleaner with the gas to see if that would help. Also check/replace the fuel filter.

Your gas pressure is too low and you may not have a large enough supply pipe. You need at least 10 inches of water column with the engine running to operate an LP vapor fueled engine. Because the engine is starving for fuel, its governor opens the throttle to WOT (so it goes to high revs) but there isn't any fuel to make horsepower with so the output voltage falls and the undervoltage alarm trips.

Check the point gap assembly for carbon tracking through the black plastic across the points,this is a common problem,also loosen and rotate the points to insure good connection.

SOURCE: I have a Kohler 7.3 ECD generator with error code UVunder frequency. Restarted gen and it ran for one hour so I shut it off. What's the problem?

check the operating rpms
the rpms determine the voltage and frequency and can be adjusted at the governor spring setting
adjust it until the voltmeter reads the required voltage
set slightly above to allow for rpms drop under load
for example if 240 volts set around 250 volts and that will drop back to 240 volts under load
if 110 set around 115 and that will drop back under full load
both frequency and volts are dependant on rpms
