I was getting the boat ready and tried to lower the unit and nothing. I can't get it to do any won't make any noise. It doesn't even try and it won't even go up, its like the button has been disconnected. I looked in the resivour and it has fluid, but like I said it not doing anything. I move it from the winter spot to the driveway and it went up then and now its sat for about 3 weeks and now won't go down. Is there a inline fuse that could be bad.
