I had the same issue with mine. It would turn off randomly last season but would always power back up. This year it wouldn't power up at all. I took the unit to be tested and it tested correctly. I purchased a new wiring set up for it from West Marine for $25 and it's working like a new unit. The fuse in the old wire was good, but there was corrosion somewhere in it causing problems.
