2019 Minnie Winnie 22R, 4000W Onan Generator. I'm scheduled to get some electrical systems work done to allow off grid camping. It includes 2 each 270 amp-hour Battle Born Lithium batteries to replace the 2 each 100 amp-hour wet cell batteries. I recently came across some comments on other...

Sooooo...... Is anyone as crazy as I am? I want to relocate the 8k Generator and use the current generator location for solar equipment. I'd move the generator to the empty space between the frame rails which is approx 3-4' away from where it is now. I currently have my Solar set up on the...

I have a question about starting the generator the first few times I used it seemed to take awhile to prime and start but worked well. The last time I tried to start it all I heard was like a whining sound like a bad starter so I stopped. The thing is brand new I’m pretty sure it’s not the...

Lost my saved configurations on my Xantrex 3012, and have been redoing them in the System Control Panel. I am on the auto gen start configurations and there are 15 types to choose from. Does anyone know that "Type" the Onan RV QD 8000 is with respect to Xantrex?

how much to you pay for a tuneup on an onboard Onan 4,000 generator ? thanks

I'm getting a low oil pressure error code on my genset. If the v8 is running, the Onan starts but shuts down and shows the low oil pressure error. It has very low hours, full oil and has been started and tested regularly until August when our world was upended. Also getting the dreaded 36 error...

Anyone have any luck finding a new bendix starter drive for the starter on a 4k Onan genny? My Onan would not turn the engine over. Once disassembled, I found that the nylon gear teeth were chewed up and very sloppy when engaging. Testing the starter, it spins fine but the nylon gear is shot. I...

Purchased used and wanting to change out Fuel, Air and Oil filters on my 8K Onan Generator. No manual. Found very little online except on how to do it. Seems pretty simple. Can anybody help as far as Filter Make and Models needed? Thanks Jeff

On a recent trip I've been having problems with the generator quitting. It first happened while driving with the generator on and the A/C running. Everything worked the first day. On the second day, the generator would quit while driving but would run while stationary. Yesterday it would quit...

I'm getting ready to do the basic maintenance on my Cummins-Onan RV QG 3600 LP generator, Model: 3.6KY-269120R, Spec: R. Cummins lists the parts needed (air cleaner 0140-3280, spark plug 01267-0275), but two oil recommendations: 10W30 or 15W40. Question #1 - which oil is better for year-round...

Hi everyone! I have a 2011 coachmen Mirada 34 BH. Just to get right down to business, here is the issue I’m having: After having changed the spark plugs, fuel pump, carburetor, oil change and air filter, I seem to have finally stopped my generator from loping and stalling out on itself. As...

Hi everyone, My 2017 FR Coachman Prism ONAN GENSET will only stay running with the OEM Converter CB in the open position, I am however equipped with solar to keep the house Batt’s fully charged. I would like to know if there is anyone that may have experienced this and if so what was your...

I am looking to upgrade to Lithium batteries on my next time to buy batteries to replace my AGMs. I use my AGS a lot especially when driving as it powers the genny to turns the ACs on/off to maintain temperature. But we also have Auto Start @Low Voltage set at 12.5vdc. That is the highest...

Our 2018 Vista LX generator has always been a little hard to get started since the day we bought the RV new. You have to prime it, crank, prime again, crank, prime again and crank. Usually on the third time it starts. I crank it for 10 to 15 seconds. That seems like it would be hard on the...

We have a wolf creek 850 on a Ram 3500 and it is built for an onboard onan 2500 LP generator. Can anyone share photos or insights into how they installed and mounted the generator in the compartment? We can’t find anyone willing to do the install and thus want to make sure we install it...

Using my generator in afternoon and evening to run AC this last trip to Texas. Everything was fine until last noon stop before home and unit failed to start. Checking the batt voltage and starting relay at unit has 13 vdc in but when energized voltage is pulled down to about 7.5vdc and...

On our 2022 Georgetown GT36K7 The Onan 7000 Generator ran fine to weeks ago, now will not Start. Checked oil (Full) Fuel Tank Full. Replaced Spark Plugs Replaced Fuel Filter. I removed the Fuel Pump and hit the prime button. Could the issue be the Fuel pump? and why is the fuel pump so...

I have a 2023 Forester Classic 2441DSF with a Onan QN4000 generator that will not stay running. It shuts down all by its self at different intervals. Sometimes it will run for an hour and I shut it down myself with no issues, other times it will run 15 minutes, 30 minutes or just 5 minutes. Does...

Up in the western plateau (8000'), generator has been flawlessly operating since day 1. OAT apx 88F. Running for 1.5 hours, left to park at campground and generator shut down. When parked, I noticed that it had turned off. Attempted a few tries to restart and restarted only to shut down after a...
