Why does the control board stop the Onan generator?
Generally speaking, the control board regulates primary functions and the most important one is to keep the unit supplied with enough diesel (or LP gas). That means the board would promptly stop Onan generator from working once it detects shortages of fuel and fuel pressure.

What happens if you run a generator all the time?
Don’t run more than one of these at a time. Your generator is also recharging your house battery or batteries, so you may be drawing more power than you know about. You might hear the generator struggle and then die. The generator may restart just fine, but even after the short built-in delay you may find you have no power in your camper.
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.
Where does the power stop on a generator?
On the genset and remote to the genset as well. That’s where you start and if you are comfortable working with A/C voltage and a voltage meter you can start at the genset and work your way through the system until you find where the power stops.
What causes a generator to automatically switch off?
The breaker is a safety feature designed to automatically switch off if a surge of electricity or overload is detected. A surge can be caused by using a device that draws more power than the breaker is rated for, using multiple ‘heavy load’ devices at the same time, or if a short occurs within the circuit.

Why is my Onan generator producing low AC voltage?
If field flash voltage seems pretty normal, the regulator could be the source of problem which you could determine simply by running 12 volts through a diode to the regulator pin 9. In the case the generator starts producing normal or slightly low AC voltages after that, the regulator is definitely defective.

What should I know about my Onan 4K generator?
Know the maintenance needs of your Onan generator. Onan has made a number of design changes that simplify maintenance. For example, the Onan 4K generator doesn’t have an oil filter. On the other hand, you have to use the right oil and never use old oil to keep the generator from clogging up.
Why is my Onan generator not producing enough spark?
Second, you can also take the fuel line off the fuel pump and see if enough fuel is getting through to the engine. A third issue may be the armature coil. If the generator is not getting enough spark, then the armature coil may be going bad and not producing the spark you need to run your generator.
What kind of gas does an Onan generator use?
For example, some Onan generators can run off both gasoline and liquid propane. This allows you to conserve gasoline when you’re away from civilization. And it allows you to switch to another fuel source to see if the root cause of it shutting down is a low gas level.
Why does my Onan generator not start up?
Check the fuel levels. If your Onan generator isn’t running, it may be because fuel levels are too low. While some RV generators will run until the fuel tank has nothing but fumes, the Onan models tend to stop working when you’re down to a quarter tank. The units that do this are the ones drawing from the gas tank.
