ok i have a 04 yfz 450 and the fan is not coming on i pulled the connections apart and ran a wire to jump the two wires on the right side(sitting on the bike) of the radiator and still no fan i unpluged the fan and hooked two wires in to the fan and the fan spins, i know there is 2 resistors in there could one of thoes gone bad would that make it not work? and no voltage to the wires any advice would be appreciated

It is to my undestanding that the fan hardly ever comes on. Unless you are doing some really hard riding then it wont come on. But I might be wrong on that also.
