Hello everyone. My 42lb thrust motorguide's steering cable broke, which I am thinking is going to be a blessing in disguise. In NJ my primary lakes i fish in it are electric motors only, so I upgraded to a 70lb thrust Minn Kota Maxxus! I just need some help on a couple of things. First off I have three 12v batteries set up to ProMariner ProSport 20plus 3 bank 20 amp battery charger. I am under the impression I need to change to a 24 v system I run the + to + on circuit breaker then - circuit breaker to + on battery 1, - on battery 1 to + on battery 2 and - on battery 2 to - on the trolling motor. Please see my Imgur album http://imgur.com/a/Rbuk9 to see a diagram of what I am talking about and all pictures. My first question is when I connect battery 1 to battery 2 what wire am i using? Same for the - on the circuit breaker to + on battery 1. Do i need a specific circuit breaker or will the 50 amp one I bought at West Marine work? My next questions is I currently have a switch that has options 1, 1&2, and 2 this controls what battery my previous trolling motor was using. Do i need to do anything special with this? From what I understand there is no battery 1 or battery 2 they have formed a super batter now (24v). My next question is I have seen the Minn Kota power cords I believe which have 3 prongs based off the youtube videos I have watched. My power adapter is 4 prongs from my Motorguide motor. Do i need to purchase a new power adapter or do something completely different to make that work? I think that is everything, any help would be greatly appreciated guys.
