So bought a 2011 polaris sportsman 850 xp eps. Love it the one ride I went with it. Got stuck and awd didn’t work. Drained fluids they were thick and black. Put clean proper demand fluid in and no AWD. I do not hear it trying to engage like I did on my 500 I am hoping it is a wire issue but how do I figure thathat out? Mainly how do I check if the power is making it to the front diff?

Thanks so much. I want too go buggying
