Was the electrical issue an under charged battery? Or a real problem?
The Ultrex was just shutting down. It was acting like an auto resetting breaker but, my breaker is manual reset. It happened once back during the Veteran's Fishing event and I discovered one of the battery terminals was loose. Thought that was all it was. Today, each time it died it took more time before it came back and eventually didn't come back. Real hard to fish without it or an anchor.
I was thinking it was the Ultrex so, I pulled out my Fluke meter as soon as I got home and was preparing to call Minn Kota. I had voltage at the power socket but not coming to through the plug to the Ultrex. I was able to tighten the screw on the positive side of the plug nearly a full turn and the Ultrex powered right up. I'm hoping to get out early one morning this weekend to confirm it's fixed. I may just eliminate the plug/socket all together if I have anymore issues with it.
