Im having issues with elec fan on/off settings. I have a Flex a lite fan with the radiator probe. Just can’t get the probe to work so I am installing a Dakota Digital control this weekend that taps into coolant sender. Crossing fingers that this will resolve the issue. You can bet I’ll start a new post if I can’t that to work, LOL! Just disappointed with the probe method but I think I was being overly optimistic thinking it would be a reliable method to activate fan.
