The problem was the red wire being open. I haven't pulled it from the cable run so I don't know what caused the break. I run new wiring along the side of the pontoon and hooked up the trolling motor which now works. Now that I know for sure that the problem was the wiring I will run the new wire in the pontoon guide underneath the boat and do the job the right way.

Don't look forward to doing this as I have done it with my front fish finder cables and it is not fun.

Thanks to all who commented on this problem
