we recently acnhored our hunter 41 (2007) and cranked up the generator for the first time this season. It ran great, then I inadvertantly cut it off, and within a few seconds before it had shut down, cut it back on. The heat light came on and now won't go off. The water is circulating, the unit is full of antifreeze, the oil was checked and I have read the manual. anyone had this problem or know what I might do next.
