Hi, I have a 2013 Sportsman 400 HO with 25 easy hours on it. Today we took a little ride, When I went to start the cold engine I noticed as soon as I turned on the key the fan was running . The fan ran the entire ride,we are in upstate NY so it certainly isnt hot out yet. When I got home I disconnected the wire off of the temp sensor on the left side of the engine cylinder.. the fan still ran. I read somewhere that the fan may go into a default mode and run when this switch is bad. Is this true or might this be another problem ? Any ideas or help is appreciated !
