Just went through this on mine. My problem was that two of the wires had worked their way off the switch lugs. I removed the fuse and took the top off and reinstalled the wires and no more problem. I noticed the wires when I unscrewed the level at the top(mine is a Barker) to get to the hand crank. I saw the wires didn't appear to be connected to the switch. Not sure why it happened.
