I have a Honda EU2200i generator and seven gallons of two year old stabilized gas that I'd like to run through it and charge my Kona EV. It would avoid taking the gas to a toxics recycler (and incidentally provide a true MPG figure for a car that can't burn gas). The problem is that the Hyundai charge cord shows a fault. Apparently the generator has a floating ground. I've tried connecting its ground terminal to a grounded water pipe and the ground pin of an outlet (both over a long extension cord) and several metal stakes up to 18" into the ground. Has anyone made this work, with this or any other floating ground generator? Any suggestions?
