Kyser Medallion Sensor

Chuck,

That sensor should be the switch that turns on the Hayden hydraulic fan cooler. My coach uses a 4 wire sensor that lights an overheat LED on the dash as well as turning on the Hayden. I bought mine from Holland Motors Michigan, but that was three years ago; I'm not sure if they're still providing parts to Wanderlodge owners. If they balk then I'd have them put me in touch with their School Bus Franchise. I've had very good experience with both their motorhome division and their school bus franchise.
