JBJ Auto Top Off Not Working

[swimmingswammi]

I bought this used and finally hooked it up. I have only one float switch. The float moves easily up and down. It is connected to the correct plug hole per the manual. I could not tell from the manual if the light for the switch should be on and what color. I tested the aqua lift to figure out which line is in and which is out. It works slow but works. The power light comes on but the light for the float switch does not. Would this mean that I need to replace the float switch? Any feed back is greatly appreciated.
