Mind did the same thing, only it was the right bottom. It didn't matter weather it was gen. or plugged in at home or campground. Then the light on the dash that tell you that you are plugged in "shore line" went out. Light hasn't blinked since. So as Steve said probably a light failing. Seems mind was the dash light. Don't plan on replacing the shore line light until I have the dash open. I know when I am plugged into the shore line from the four red lights and don't know why they have the other light in the first place. Maybe there is a good reason.
