I bought a small generator for a 4 day camp trip. I left it in the truck. Used it to air up the bed, lights at night and coffee in the morning. The last morning the yellow reset button wouldn't reset. The lady at the shop said, "you didn't ground it, did you?" A simple ground is to stripe back the insulation about a foot on the wire. Wet the ground down and park a tire on it. Everytime out, add more water to the tire. Pee on it if you want to.
