My brother bought one of these bikes a couple months back and the previous owner had a toggle switch wired to the fan switch (lower sensor / switch in radiator). Today we removed the toggle switch, and installed new oem fan switch and the switch sensor. The fan will not turn on with it setup how it should be. With a cheap test light I am getting power to the sensor and the switch. Anybody know what the heck we should do as the next step to get this fan working?
