I bought a 98 Vulcan 800A. The fan only came on when the motor warmed up... then after shut off it ran for a few minutes then shut off. Last week it didn't come on any. So I checked the fuse and it was blown so I replaced it and it still didn't work. So I bought a new Temp Sensor and fan switch. Now it comes on as soon as I turn the key on and runs the whole time I ride it, then when I shut it off it shuts off as soon as I turn the key off??? Maybe they gave me a wrong switch or maybe a short in wiring???? Any idea?
