Have a watchdog battery back up system for my sump pump.Battery back up was coming on all day as main pump was not working. Got a new sump pump. That didn't work. Found out is was the float switch that was bad. Fixed that, and now red light on back up system will not go out.The green light is on stating system is operating and battery @ 100%. Tried pushing button in, but red light will not go out. Any ideas as what the problem may be?
