I have a Delta Pag pretty straight H/L control. 1 40 amp inline fuse from the battery and a heat sensor to the radiator. Pretty bullet proof. I didn't check to see if the sensor wire may have come out.
The heat sensors can be problematic from everything I’ve seen. I run a Dakota Digital controller on the contour fans with a separate temp sender. For a Taurus fan that controller would actually be an easier set up.
But it sounds like there’s still some troubleshooting to do still. Check the sensor, make sure you’ve got power everywhere, that sort of thing. I hate tracking down all that electrical stuff myself, easier said than done. But if your setup worked well before it’s probably an easy fix once you’ve found the gremlin.
