I have two X50 DS Lowrance's. When I shut the main power switch off on the console which shut off both fishfinders and then turned the power switch back on, I hit the power buttons on the FF's andd the dash mounted one won't come back on. The bow mount is working. Is there a 3 amp in line fuse on these as the book recommends or are they wired right to the fuse box? Are the 2 FF's wired on different fuses? I'm going to call Skeeter to see if they can solve it, but thought I'd ask here on the boarrd. The dealer (100 miles away) says I need to find the power lead from the bad FF and check it. Because these are the standard FF's that come with the boat, they should all be set up the same from the factory. Thanks Big Al
