Do any of you have an issue with your trolling motor coming on and off by itself? a friend of mine has one that has been doing for quite a long time and yesterday when I was working on my boat I kept hearing a soft beep I was working on my dash couldn't figure out what was beeping then realized it was my Ultrex doing the same as his it is off and then comes on by itself and then off again. Anyone else ever came across this or what would be causing it???
