08 kfx 450r cooling fan problem

Ok Guys, Here is the problem I am having....My cooling fan will not kick on. First I checked the fuse, it was good, I went through my relays testing them from the fuel pump. I ended up having 2 relays bad, but that wasn't my problem, still overheated. I unplugged the fan and tested it, the fan is good. I then went to my cooling fan switch in the back of the head. I unplugged it, took a paper clip and crossed the plug out, the fan didn't come on, so that tells me that the cooling fan switch is good. So I got my test light out and checked both terminals on the plug, it never lit up. So that tells me there is no fire in the plug to the cooling fan switch. I am thinking I may have a bare wire maybe grounding out, or a naked place in the wiring somewhere. So I am posting this to see if anyone has had these issues, or if anyone can help me in the right direction for fixing my problem.
Thanks a lot and God Bless! Adam

if you unplug the coolant sensor on the back of the cylinder the fan should run all the time but with the warning light on.
