Last year I installed a winch on my 2010 Polaris 850 Touring EPS EFI. Seemed to work but have never really used. Today I installed a Polaris snow blade. With the ATV running, I used the winch to raise the blade, everything seemed to clear and work ok. I then used the winch to lower the blade and the ATV turned off. Everything electrical is dead - nothing happens when I turn the ignition key. Sounds like I threw a breaker/fuse. Where do I look for a main breaker?
