SG-

Thanks for the fast come back! Sorry if I didn't makeit clear. I do not have a 3 way switch; rather I have a breaker that is the on-off fof the manual mode, and I have the 3rd wire connected directly to a hot source with a fuse in the wire. When I remove that fuse the pump shuts down. With that wire removed the pump still works from the on-off breaker in manual mode.

Thks.
