Hello! I am new here and very new to ATVs! I got a used Yamaha Grizzly 700 2010 a couple of weeks ago and it was ok until a couple or rides after. Tha machine stalled and then did not start any more. Batter seems fine, I replace the starter selenoid, I am about to replace the throttle position sensor but hey, I found tha blac cable comming from the negative of the battery not connected anywhere! Where should I connect it?
