A generator allows you to use power when dry camping.

If you do much dry camping or boon docking, the generator is an important accessory in your RV. The main job of the generator is to run a load and charge house batteries. A generator will pick up the lost power if the land power blacks out. You can also use the generator to run the roof AC while driving down the road. The generator will kick off when the gas tank reaches between a quarter and half tank, so that you don't run out of gas. When problems occur, there are a number of ways you can repair the generator on your own.

Check the circuit breakers and replace the broken ones if the the generator is running and there isn't any AC power.

Change the fuel filter, as well as the genset. A black/brown substance around the exhaust shows that the fuel filter should be changed.

Inspect the DC cables behind the genset to make sure they are clean and tight. If they are dirty, clean them with a mild cleanser and tighten them with a screwdriver.

Remove the screws from the cover and check all wires for loose connections.

Check the oil to see if it is low when the start/stop switch flashes. If it is low, add as much oil as suggested by the owner's manual.

Tips

  • Charging house batteries weekly for 30 to 40 minutes will stop the carburetor from clogging fuel jets.
  • Change the oil and filter after every 150 hours of usage.

Warning

  • Use only generator manufacturer's replacement parts; otherwise, your warranty will be void.
