I really appreciate your post on this. I did not realize this problem could exist. I need to pull mine just to check it out. Hard to believe a technician could affix two battery wires on a block and not tighten the nuts.....good grief. I have not had the problem myself, but I really thank you for bringing it up. It could save me an issue on the water one day....lot better to check it in the garage than in the middle of the lake. Thank you.
