You'll have to post the make and model of the generator to get any advice that's worth anything. If not for the generator (best), at least the make, model and year of your motorhome. Someone may have the exact same model and the experience to help. I usually recommend you create a signature which will appear with all of your posts with RV information just for this purpose.
If you have that information (on the gen set) you may be able to find a manual for it on the manufacturer's web site. Pretty much every manual I have for anything I was able to copy from the manufacturer's site.
