Brought it outta the box, Cleaned it up from winter storage and it will not crank. Brought it out back in January and let it run for about 10 min, Started and Ran fine. Now it wont do nuttin. Replaced battery with a new one, Fuse in the power box is good. I been at an auto dealership for 23 years and have general knowledge but -0- when it comes to this thing. Can anyone point me in the direction I need to go to start checkin this thing out?
