24 V Trolling Motor ?

[Coon]

If all i'm using the two batterys for are the trolling motor and maybe my nav lights, do I need a in line cirquit breaker installed?? This is my first time with a boat and i'm quite ignorant bout the whole thing...

[bobbymalone]

yes you should wire in an inline breaker. any circuit should have some sort of fuse/breaker for safety.

Make sure you wire those batteries up in series rather than in parallel.

and I bet your nav lights won't like 24V at all. Stick with 12V for that stuff.

Ok thanks and what's the difference between series and paraell?

[Esox_Magnum]

Series is 2 batteries hooked up battery 1 pos lead to battery 2 neg lead you hook your trolling motor to the other 2 open post making it 24 volt..

Paralell is hooking 2 12 volt togeather hooking both pos and neg togeather to each battery keeping 12 volt but doubling reserve time...

Ok right that's what i'd plan on doing thanks for the clarification.

I'd keep your trolling motor batteries separate from the rest of your accessories. Run everything else off your starting battery.

Does someone have a pic of an inline fuse and how they hooked it up for their 24V t-motor?

Just install a 40 amp or 50 amp self re-setting breaker at the battery in the red positive wire shown in the great illustration above.

I have had better luck with the 50 amp breaker.

Wire accessories to your 12 volt starter battery as mentioned above.

80# Terrovas take a 60amp breaker, 50 amp works with any of the smaller 24 volts...

If you are going to use an onboard charger, or any charger, you will have to separate the batteries each time they are charged as charger has banks, meaning it charges each battery independently. My boat had a switch already installed that can be selected to operate the batteries in 24v for the trolling motor, completely separate them for charging or use one as 12v, has a 50 amp breaker between switch and trolling motor. Third battery for starting and accessories that charges on the motor as it is used and then on board at home.

Not true for many onboard chargers. Mine, for example, the bank outputs "float" so it will charge the batteries still connected in series.

I have never unhooked mine either with todays new chargers just plug them in when not using the boat and forget it untill you go fish again... I'm also a firm beliver in a charger for all batteries including the cranking battery even though the motor does charge sometimes you use more power than the motor can recharge...

+1 I won't be with out a three bank charger so all i have to do is plug in the unit, and know the next morning ALL batt. are charged! :)No seperating battery leads or any of the other head aches. Just check the water once in a while and you're good!

[Cliff Wagenbach]

I agree also. I have never unhooked my charger.

Just put it on the positive post and tighten it down with the wingnut and that's it? Doesn't it need to be in a circuit?

Can't quite tell if you don't understand or are a wisenheimer, but as he said it goes in (series with) the red wire (the positive lead) that goes to the trolling motor.

[EBass]

I don't understand how it would work if the breaker is just on the positive post.

Meaning, I put the breaker on the positive post then the positive lead connects to the breaker? Correct? Maybe I bought the wrong breaker. So yeah I don't have any fuses for my Minnkota and I know that's asking for trouble. Looking for help is all.

[delcecchi]

Yes, the breaker connects to the battery, and the trolling motor connects to the breaker. Just like in your house. That way if something goes wrong, the breaker trips and no current can flow to cause bad stuff like melted wires or flaming boats.

battery >>circuit breaker >> trolling motor>>

Thanks Delcecchi - I just need an connection adaptor for the wire to connect to the breaker. It has a metal plate on the breaker that confused me, but that's easily done. I'll put on the breaker this week, if I can find it. Ugh.
