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.

SOURCE: Hello, I have a Kohler Marine Generator that says OC on the menu when I try to start it. Any ideas?
OC stands for Over Crank. How long does it take before the genset starts?

Did you remember to set the overspeed shutdown threshold on the control board?

Check the connections on the tranfer relay and two coils. The two coils have blue wires. I have seen them come off from assembly or shipping its common. Each coil has two blue wires #8 and E1 with crimp steak ons and limit switches make sure there all pushed on all the way. Hope this helps

Hi Scott,
Since the generator starts but there is no power to the control board, there is an electrical problem inside the generator.
First check the circuit breaker at the back of your generator. If the breaker is on, then your generator is in serious trouble.
Call a repairman, but also keep in mind you may need a new generator.
Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,
Handie Andie
