RV Gas Generator Annual Maintenance, Detailed Program & Tips, exercising the generator properly & some safety tips.

I highly encourage you to watch the entire 3 Part series. There’s a lot in this RV gas generator Master Class Series for everybody, even if you have a slightly different RV gas generator model than we do.

There’s a lot to know about taking care of your Onan RV Gas Generator. These annual maintenance generator items you should be doing are not difficult to do. They are all DIY.

I decided to break everything down into a 3 Part Series:
Part 1 will cover basic maintenance you should do every year:
   • CUMMINS ONAN RV GAS GENERATORS  ULTI...  
Part 2 will cover a more detailed look at all the different parts and areas you need to know about, their maintenance schedule, some trouble shooting tips and cleaning the slip rings:
   • CUMMINS ONAN RV GAS GENERATORS  ULTI...  
Part 3 will cover Fuel Tips, the importance of PROPER EXERCISING and some safety tips:
   • CUMMINS ONAN RV GAS GENERATORS  ULTI...  

This series will show you how to keep your generator running top notch & help it last for 10’s of thousands of hours.

We do all our motorhome and Onan generator maintenance every year BEFORE we head out on the road for another year of RVing. RV generator maintenance is important. This annual, scheduled, RV generator preventative maintenance is an easy DIY job. We do most, if not all of our motorhome and Onan RV 5500 gas generator maintenance in the winter & sometimes it runs over into early spring. Everything we cover here are the basic things you should be doing to your generator all the time. You don’t want to wait till your RV Gas Generator breaks down, has gas or fuel problems or doesn’t run right and then decide to deal with it.

This 3 Part Series covers cleaning the outside of the Onan RV Gas Generator, changing the oil, changing the oil filter, changing the air filter, cleaning and checking all the electrical contacts, cleaning out the Onan generator spark arrester, changing the spark plugs, exercising your generator, the oil pressure switch, trouble shooting and safety tips. I encourage you to be proactive and do these annual scheduled maintenance items now.

How I exercise my generator when parked:
• Turn off all appliances inside the coach first. AC units, fridge & anything else that’s running off shore power
• Go out the electrical pedestal & flip off the breakers. That way no power is going to the coach coming from the pedestal
• Start the generator up, let it warm up for about 35 minutes, then go back inside the RV & start turning things on to put at least a 50% load on the generator
• Let the generator run for about an hour.
• Turn everything back OFF in the RV. Con't to let the generator run for about 5 more minutes to cool down properly
• Shut off the generator. Then go turn the breakers back on at the pedestal & then turn everything back on in the RV as you normally would.

DISCLAIMER:
We are in no way experts or professional mechanics. But being a journeyman millwright for years & being EX Military, has proven to be very helpful in my lifetime learning how to care for & maintain all sorts of machinery & equipment like: helicopters, airplanes, tanks, motorcycles & many types of other vehicles. That, along with 18 months preparing & upgrading our RV before we went full time, & now traveling for several years has gained us a lot of knowledge. Regardless of what we recommend, consult a professional if you're unsure about working on your RV. Work you perform or products you purchase based on any information we provide is at your own risk.
