12 volts to 24 volts

[Darrendude]

Is it possible to run a 12 volt trolling motor on 24 volts? What componets would you have to change , if any? If you run 24 volts , the amps would be less, right?

Re: 12 volts to 24 volts

No, not if it's a 12V only model. Some have a 12/24 switch. You're better off just hooking the 2 batteries up together, pos to pos, and neg to neg, this will double the amperage/life. (forget whether that's called series or paralel)

Re: 12 volts to 24 volts

Connecting them pos to pos and neg to neg is a parallel connection.<br /><br />Unless you have a trolling motor with a 12/24 switch, connecting it to 24v will provide a good demonstration on the priciple that all things electrical run on smoke. The smoke is contained in the wires, motor, etc.<br /><br />Put 24 volts on the system and you will let the smoke out and the trolling motor will not run anymore.

Re: 12 volts to 24 volts

Ok , put it this way. What is different on a 24 volt motor opposed to a 12vt motor? I know 24 volts, you have less amps, so wires can be smaller, right? Is it just a matter of changing a couple switches to run 24 volts on a 12 volt motor?

Re: 12 volts to 24 volts

It's a different motor. I don't know the principle of it. But I do know you can't turn a 12 volt motor into a 24 volt motor. I had the 36 volt Minn Kota on my last boat, did a lot of research on TM's before I bought it. And I never heard switching or changing to brought up. You get what you get when you buy it..................

Re: 12 volts to 24 volts

Luna my trolling motor is a 12/24 volt. Just want to know what is different in the 12 volt and 24volt motor.and what makes a 12/24 motor diff from a 12 vt only motor. I have had mine apart to many times for my liking and they seem pretty simple. What is the weak link, where will the smoke leak out? lol<br /><br />Thanks

Re: 12 volts to 24 volts

I will do a test and report back. I have a very old JCPennys 12 volt trolling motor. I will try it on 24vt next time I go out. Any predictions?

Re: 12 volts to 24 volts

Ah, I thought you were talking about converting a 12 to a 24. I can't imagine how they make these dual setups. I would figure the 12 and the 24 would have different windings or whatever. <br /><br />So hook the neg to pos and the pos to neg I guess to get series/24 volt. Can't hurt to try....<br /><br />Good Luck!

I suspect it will work better than you expect for a few seconds, maybe even a few minutes, then the smoke will leak out and it won’t go any more. Since you are willing to experiment with going out on your boat and setting it on fire, I would like take this opportunity to thank you for your participation in this forum.<br /><br />You’re right, in general motor’s are pretty simple technology. It’s all in the winding; a balancing act between too much voltage and too little voltage. Either one may let the smoke out, set your boat on fire, and feed you to the sharks.<br /><br />Darrel, unless you are committed to becoming the poster child for California’s public education system, I strongly urge you to limit this ‘experiment’ to your driveway, if at all. Then you can walk over and throw the thing in your garbage can and have beer with a good laugh.

Re: 12 volts to 24 volts

Darren,<br /><br />My thoughts<br /><br />At no load the engine will spin faster with 24v than with 12v. As you apply load and reduce the rpm so the current draw will go up. > voltage = greater current draw as the resistance increases therefore you can run you motor fine on 24v but you will be able to put more torque onto it and cause the current draw to go up past what the windings can take hence the smoke. This is all assuming its only rated for 12v. But yes for the same hp you will draw less current it just depends whether you will put more torque on the motor.

LMAO<br /><br />unless you are committed to becoming the poster child for California’s public education system, I strongly urge you to limit this ‘experiment’ to your driveway<br /><br />I think I will try it in my driveway with a trash can full of water. Good point. Its and old POS motor, probably 1970's . I came with the boat and I was going to toss it anyways. I will let you know what happens.

Re: 12 volts to 24 volts

Lets take a poll on how long do you think it will run on 24 volts.

Re: 12 volts to 24 volts

Here's a question: What happens when you hook up a 12v light bulb to 24 volts? Motors don't go nearly as quickly, but I would project similar results.<br /><br />In a 12/24v motor they take the windings and cut them in half. For 12v the switch connects the windings in parrallel. Fro 24v they connect them in series.

Re: 12 volts to 24 volts

Gee,if I can find a way to do this to my Norelco,I can shave in half the time ! I can just rewire the plug and connect near the clothes dryer.No sweat !<br /><br />DHP

Re: 12 volts to 24 volts

Jack L, is correct. Two windings 12 volts windings wired in parallel and 24 volts wired in series.

....Unless you do what I did when I was about ten years old. I literally did just that with a couple 6V lantern batteries. Criss crossed their terminals with aligator clipped jumpers (without any load inline), then another set to the AM radio I was playing with. 12 Volts, worked fine for a few minutes until the latern batteries started losing it because of the direct short in parallel to the load. Those alligator leads did get warm though! I was so disappointed because I could have enjoyed messing around with those batteries for months had I been paying attention.<br /><br />It could get downright exciting if someone were to do this with a couple 12 volt batteries! By the way, I know you didn't mean it that way, Luna. The load leads would be the second set of positive and negative- it just made me remember that incident 35 years ago. It was for me a good lesson well learned.

Re: 12 volts to 24 volts

Bearcat - The short circuit capacity of the new 12v AGM marine batteries is in excess of 4000-amps. You think things are going to get warm?

Re: 12 volts to 24 volts

Before you destroy a good trolling motor why don't you go buy a 6 volt light for your car. It is a lot cheaper than a trolling motor. Light will burn very bright for a while like a flash bulb.

Re: 12 volts to 24 volts

Its not a good trolling motor. Its a piece of junk that I wil be tossing.

Re: 12 volts to 24 volts

darren<br /> the windings are inside the motor. when you use the 12 volt side of a 12/24 *all* the electro magnets (coils) are used. when you use the 24v side half of the coils are used to get the mfgrs output, if you want to buy a new motor try it
