I purchased a low cost float switch to install in a water trough like the one pictured below. I wired it to a Sun Pump PCA-30-M1 controller. I have a DC water pump, solar panels, batteries and everything else I think I need. I connected everything in the back yard to test the set up before I took it out to my well. Everything worked fine except for the float switch. I checked the wiring to the controller and closed the switch manually on my work table. The switch would not turn the pump off. Anybody have one of these? Any suggestions? Thank you.
