12/24v system on trolling motor

[KDAVID1]

I am installing a new trolling motor. Going from a Motorguide 50lb thrust 12/24v system to a Minn Kota powerdrive v2 24v system. I currently have two 40amp cb's-once for each battery. will I need to change both to the recommended cb voltage or am I good with two 40amp. I think Minn Kota says to use a 50 or 60amp cb. Any help would be appreciated.

It's the amperage, not the voltage.
Yes, you will need to change them.

Both of them correct? Just making sure. And thanks for the help.

You need to make sure your batteries are wired in series then use 1 breaker at the positive terminal.

Thanks. Looking at mine I think they are parallel. It is the Comanche package so it haw the two cb's one for each batt. and also has wires going to a center connector of some sort(which acts like a cb as it can pop and need to be reset) below the cb's with one end going to one bank (pos. and neg) and another set going to the other bank (pos. and neg) all running up front to a 4 wire female with a 3 wire male (from the trolling motor)

The diagram above is correct but if you are a cheapskate you can put the two 40 amp breakers in parallel and it will trip out at approx 80 A .....thats recyleing ....

Re: 12/24v system on trolling motor

You have a typical 12/24 volt system where each battery has a pair of wires running independently to the four terminal receptacle. You do not have to change any wiring but you do need a 12/24 plug. Those plugs have a jump inside them for creating a permanent 24 volt only connection. If you do want to use the posted diagram, then simply disconnect one pair of wires from just one of the batteries. Don't remove them from the boat as the next owner will thank you. You then wire the two batteries as shown. You will then have 24 volts at the receptacle and you will only need to determine which two terminals deliver that voltage. The mating plug will not need the jumper but the two wires to the troller will need to be matched to the receptacle.

I dug more into the boat today--took out all the stuff so I could get to everything. I found that the two cb's I originally thought were part of the trolling motor system were not. And the thing that the battery cables went to was actually two separate post type cb's. So this will not be as bad as I thought to change these. Two 50amp cb's and I am good to go. The wiring diagrams on this show a bit different than what I see. On the connector--I took a look at it and the two wire as stated in the above post will be not problem--power to the side with the connecting strip and ground to ground. I dont know why electrical has always been such a hard thing for me but I'm learning. Thanks for everyone's help. (I'd take pics if I had a camera--mines busted)
