What does the Governor do on an Onan generator?
These Onan-powered generators are often found on recreational vehicles or in other instances where consistent electricity is needed to operate a few electric lights or appliances. An Onan engine is protected by a governor that will increase the speed when a greater load is applied, or reduce the RPMs when under a lesser load.
When does the generator shut off in an RV?
The generator in my RV shuts off after running for approximately 25 mins, with or without a load. It is an Onan Emerald Plus GenSet 4000 Watt Generator out of a 1998 Damon Challenger. Gas tank is full.
How do you adjust the speed of an Onan engine?
Follow this spring back to a bolt through a mounting flange, with a nut on the opposite side. This is the speed adjustment nut. Turn this nut with an open end wrench and pay attention to the engine speed. As you tighten the nut, the engine speed should increase, and conversely, as you loosen the nut, the speed should decrease.
What do I need to start my Onan generator?
Getting the Engine Running Before any evaluation of the controls, regulator or generator can proceed, the Onan engine must have oil and fuel, be in running condition and the 12-volt battery charged. The electronic governor, 151-0752, on Models BGM and NHM, Spec B and later, must be functioning properly.

What happens when you start a generator in an RV?
This is what normally happens when you start your genset. Pressing and holding the start switch causes the control board to send 12 volts to the ignition, fuel pump, choke heater, start solenoid and field flash circuits. The engine then cranks and starts. Oil pressure and generator voltage build up within 1-2 seconds.
What happens when you turn off the genset?
This is what happens when you stop your genset. Pressing and holding the stop switch for a few seconds causes the control board to cut off the 12 volts to the ignition and fuel pump (and/or fuel solenoid valve) causing the engine to stop. On models equipped with magneto ignition, the control board grounds the magneto kill circuit.
