When the dealer wired it, he had the two trolling motor batteries and the starter battery in the rear of the boat. It was to much weight. I am moving the trolling motor batteries to the front.

The dealer had a volt 20 amp swich at the console up positon was for 24 volt and down was for 12 volt charging. The switch has been to light for the amp. I have to replace it every year because it gets toasted. I was usng two battery chargers to charge both the batteries. I have to put the switch to 12 volt during the charging.

Maybe use a relay amp in lieu of this 20 amp switch. I know enought to get me into trouble. Help I also bought a new 2 bank duel pro battery charger. I want to wire a new system using my trolling motor and new battery charger. Maybe some one could e mail me a diagram?? Thank you. July 20th, , Comment Post Cancel.

July 23rd, , Also, I want to connect the starter battery to the trolling motor batteries. Inorder to either charge the trolling motor batteries with the generator or jump the starter battery should it be drained. I was told that you need a isolator? Can I e mail with a diagram of my boat battery layout. If you were running 12 volts, it would be easy. The problem is, everything has a common ground. As such, you cannot charge 24 volts with a 12 volt system.

In order to charge your trolling batteries with 12 volts, you would have to disconnect them in series and re-connect them in parallel, which could have some complications. Now, if you have a dual-battery charger it MAY be able to charge both batteries while they are still connected in series. It deals with common ground and floating ground, and gets more in depth than you need anyways. Your battery charger literature should tell you if it is possible or not. July 24th, , It seems from your other posts, you know your stuff.

I am moving my batteries up front and want to wire my own system. In the old system, they ran and made the 24 jump at a 20 amp 3 way toggle switch, which toasted over a long draw from the trolling motor. The things I want to do are: Use my new 2 bank dual charger to charge my trolling motor batteries when pluged into v. Jump my 12 v starter battery from one of the trolling motor battery. Charge all three batteries while running the outboard motor.

I have a diagram that I drew up for Items I to 3. The diamgram uses 4 buss bars. The diagram is as follows: Batt 1, 12v and Batt 2, 12 v trolling motor and batt 3, 12v starter. Buss 1A pos and buss 1B neg for Batt 1. Buss 2A pos and 2B neg for Batt 2. Buss 1B neg jumps 2A pos for 24 v. The battery charger per the manufacture said that each bank is isolated. This is the system. I just dont know if it will work? July 26th, , Your diagram for your trolling motor batteries is obviously very simple, they are connected in series, and it sounds like your battery charger can handle this without disconnecting them.

Now, you also want to be able to jump your starter with one of your trolling motor batteries, which would mean puttin it in parallel across ONE of the batteries not both. This is also possible, and you don't even need to break the series connection between your trolling batteries. But, you certainly do NOT want it connected in parallel all the time. Now, this is all very simple if you wanted to keep both systems seperate, with the occasional jump start.

If you want to charge all three batteries with the outboard, things get infinitely more complex. At that point, you would need to break the series connection between your trolling batteries, and connect them in parallel, and then connect that in parallel with your starting motor. With all these parallel connections, you can develop large loop-currents, which isn't a good idea. I'd then recommend isolators between the batteries to eliminate the loop currents, and with so many connections and dis-connections, it becomes extremely difficult to do with one switch.

July 27th, , Let say for the moment, I dont do the charge all three batteries with the motor alternater and just do the jump one trolling motor battery to the starter battery Batt 3 pos to buss 2A pos and neg to neg buss 2B. What is the best way to wire for this condition? My diagram shows it connected in parallel all the time. Meaning, The starter battery and one of the trolling motor batteries batt 3 would be under charge all the time from the alternater? Would this circuit have to be broken with a switch.

Would one of these both battery switches work? If I used a switch to break the circuit and the starter battery was drained, when I flip the switch to jump the dead battery, the dead starter battery would draw all the power from the trolling motor battery. Would this harm my alternater? What is the best way to wire for this jump condition. Would a isolator work here too. I wish I could sent you my diagram.

Maybe from the discribtion above you would draw it out. What size isolator and switch would I need to work. I looked up a site called onlinemarine. They have many switches and isolators. Cheak them out. Maybe you would advise me on the ones I need, in order the make the system work?? July 28th, , What is the most advertised aspect of a starter battery? Cold Cranking amps, or CCA. Forget the cold part, and look at the number. It's usually amps or more. Why do you think that is? Because your motor often requires several hundred amps to start it up.

Now, amps is for a big-block cubic-inch V8, so I doubt your outboard requires amps, but it's entirely possible to require amps, maybe more. Does that mean you need a switch rated for amps? Not quite.

Both the 24v and 36v trolling motor wiring diagrams are listed below along with the Simply wire each bank of the charger to each battery accordingly. Jumper Wire - If you have a 24v or 36v trolling motor you will need short lengths of wire to connect your trolling motor batteries in series. Make sure to buy the.

It works by automatically putting two 12 volt batteries in series when you need to run the trolling motor and in parallel for charging. It is bi-directional so when not trolling, the trolling booster battery backs up your starting or house battery.

I then have 4 wires in my battery compartment from when I purchased the boat it is suppose to be wired for a 24V motor. I can get power running all combinations of wires; execept running the red on the pos.

How Do You Hook Up Trolling Motor Batteries?

Erik Landesfeind explains how to wire a trolling motor in this detailed summary of the process he used to fix a electrical problem on his boat. I ran into just that situation last month when my motor stopped working. After spending hours beating my head against the wall trying to figure things out, I broke down and called Nick at the Trolling Motor Doctor in Long Beach. After checking out the motor itself and giving it a clean bill of health, Nick explained my problem lay somewhere between the batteries and the motor itself. After looking everything over I noticed quite a bit of corrosion on the plug from electricity coming in contact with the marine environment so I decided to start from scratch and replace everything. I started out by making some new battery cables. Since I replaced the normal battery cables in the boat with a heavier gauge I had to get an adapter that would accept the bigger wires into the plug. I went with the bigger gauge wires to minimize voltage loss over the foot wire run between the batteries and the trolling motor. To prevent water intrusion into the plug and adapter assembly, I packed everything full of Marine Electronics Grease.

Learn how to connect two 12 volt batteries to make one 24 volt battery unit.

Wiring for a 24 volt trolling motor requires basic electrical skills and tools. Understanding the theory of wiring in series and parallel is helpful, but not necessary. A 24 volt system will need two additional 12 volt batteries and extra equipment to keep them fully charged. A cut off switch should be installed so the batteries can be easily separated for charging.

Posted on Jan 02, Posted on Oct 20, The method described is proper, but the name of the method is wrong. On the female plug for the motor on the boat, if you have the wiring for TWO separate batteries coming to the plug, the male plug must have a jumper in it. To find out, disconnect the batteries one at a time and voltage check to see if there are two separate battery systems there. There probably are.

24 Volt Trolling Motor Battery

Trolling motor plugs function like plugs you find in your home. There are two components: When you remove the plug, the electrical connection is broken and you can then remove the motor safely. Follow these steps:. Find a surface on the boat where the structure is strong and out of reach of a lot of water. Put the receptacle in the newly drilled hole and use the small holes on the side of the receptacle to mark where the screws will go to hold the receptacle in place.

How To Wire A Trolling Motor

Installing a new trolling motor on your boat is a relatively simple process, but you need to have the right equipment and parts. Below is a list of the parts that are included with your trolling motor and other parts recommended and required that you will need for installation. Once you have the required parts for the installation, you will want to be sure that the trolling motor is wired properly to the batteries. To do this, identify the positive red and negative black power leads and attach the leads properly to the battery. The positive leads of a 12v trolling motor system usually trolling motors with 55lbs of thrust or less will attach to the positive battery terminal, while the negative lead will attach to the negative terminal. If you have a 24v or 36v trolling motor system you will need to attach multiple batteries in series.

One of the great jobs in the Man Cave is rigging, maintaining and working on our boats. We love working on tackle but there is something special about boat work. Whether it's a new one like the Polar Kraft TX , the Ranger Z or even the old washtub, the Ranger Banshee , there is always something new to add or something to do on them to make them work more effectively. All of us at Wired2Fish are detail oriented, love challenges and that carries over to our equipment. Installing new electronics, shallow water anchors, or our recent project, changing a 12 volt trolling motor to a 24 volt one takes careful planning.
