I don't remember where it's located on the Duke, but I think it's in or next to the thermostat housing. Should be a single wire sensor.
If you're testing the circuit by using both wires at the fan, that may not work due to the ground coming through a closed sensor at high temperature. It would have to be grounded to the chassis somewhere up front.
