How do I manually start my RV generator?
To prime your generator, push the prime button down 2-3 times and then hold the start button down until the engine starts. If your onboard generator won’t start after 3-4 seconds of holding the start button down, release the button and repeat the process.
How do you jumpstart an RV generator?
Connect the red positive (+) clamp on one end of the jumper cable set to the positive (+) post of the vehicle battery, then connect the red positive (+) clamp on the other end of the jumper cable set to the positive (+) post of the Onan generator unit’s battery.
How do I reset my Onan generator after service?
Hold down Stop/Prime and it should show a steady red light. If not repeat above. If it has a steady red light on Stop/Prime then start the generator as usual. Once it stabilizes turn on the breakers.
Can I jumpstart my generator?
A gas-powered generator can indirectly jump-start a car, as the electricity it produces can power a battery charger, but some chargers also facilitate a direct jump-start.
What does the RV Generator Control Board do?

Why is my generator not working in my RV?
If the generator won’t run, or runs sluggishly, and there are no fuel, oil, or connection problems, the generator itself may be bad. But the problem is usually the fuel filter (which can become clogged, especially when using diesel). Fuel filters are common culprits but they are pretty cheap to replace.

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.
What causes a generator to shut down at low oil level?
This can be caused by low fuel level (not getting gas), vapor lock (too hot, gas is boiling), fuel contamination (water or dirt in fuel and/or filter) or a faulty fuel pump (insufficient fuel pressure). Models equipped with low oil level (LOL) switches will shut down the engine on low oil level.
Some RV generators are stand-alone units and do not have a fuel line connected to your RV fuel tank. So, in some instances, your fuel may be low in the generator itself. Another common scenario is the fuel has been sitting in the generator between travel seasons and is just old.
