I’m trying to wire a float into my skimmer lid so if it overflows it shuts off before filling my Co2 scrubber. I have 2 different floats, both are open when down, closed when up. I’ve tested continuity multiple times. When I wire into BoB it switches to closed and will not switch to open regardless of position of float. If I ground out BoB it does register open and close, has anyone ran into an issue where certain floats resistance values don’t work well BoB, I get about 2 ohms resistance when open and about 500k when closed, if I read on continuity I get beep when down(open) and an open line/no beep when up(closed). Any info would be appreciated. Thanks
