Hello all. I have a 2008 Hunter 45 DS. My forward head keeps filling as if I have the fill switch engaged. This started after I used the switch to fill the head. It kept filling like I was still holding the button down to fill the head. I first thought the switch was stuck on so I pulled the switch and disconnected all of the wiring connecting the switch. No luck with that as the main pump for both heads engages when turned on. I would not have thought this was possible since power to the solenoid should be coming through the switch. I guess that isn't the way it is wired. Any suggestions on how to proceed before I take everything apart?
