When I turn on auto fill on both sides, together or individually, the light on the switches turn on and off real fast. Like this, tick, tick, tick.......I thought it might be pump wiring, so I disconnected all pumps and still doing it. My question is... Could my timers be bad. I assume that's what those can-like things under console are. Mine are red and about the size of a Vienna sausage can. Anyone heard of this happening? It doesn't do it when I manually fill the wells, pump out or recirc. Just auto fill.

Nevermind. Figured it out. It was the timers gone bad. Replaced those little can things, works fine.
