12v winch

Post by DDD »

Hello all, I am new here and in the process of purchasing a '74 710m. Flying out Tuesday and All I need to do is exchange funds and ship it it home.

My question: Is there a reason why one cant split the voltage by tying into only one of the two batteries for high draw items like a winch?
Could the leads for the winch be attached to the positive and neg terminals of only one battery giving the necessary 12 volts of power?

Thank you,
Darryl

Not very practically. It could be done, but there are risks of wrong hookup and charging problems due to mismatched voltages.

is possible, doable BUT ,it doesnt work..... once you do a full power pull, the 1 battery taking the load goes down in power and the other battery fully charged restrain the charge from the alternator....been there, done that. doesnt work... :cry: :cry:

Welcome to the forum!
Once you get your 710m post some pics for us
Fill in your location so we know where you are
And finally do a search for 12 volt - it has been discussed here but basically as others have said once you draw down one battery it will not charge correctly and you will be replacing batteries like crazy!
Cheers,
Dan

Got it, makes sense. Already secured a 24v winch and will fabricate a custom heavy duty bumper and mount.

I will post some pics when it arrives.
Thank you,

Ok, so what is the proper way to get a 12 volt system out of the 24 volt system?

Reason is here in the US the: winch, Cigarette lighter for GPS and Phone charger and such, trailers, CB radios and such run off 12 volts.

So what would be the proper way to create a 12 volt system to tie these things into?

This is the same post you just made
No point in asking twice :)
a 24v winch draws less amps so there would be no purpose to try and run a winch at 12v on a 24v truck esp. via a converter - you would spend more on an industrial converter than the winch (perhaps even more than the truck) to try and get 250-450 Amps! :shock:

Don't know how to link my reply in the other 24v discussion so I will repost here.

I have a different sol'n for this problem. My 710 has two 12 volt batteries connected in series to give 12 + 12 = 24v. Each battery has 2 + and 2 - posts and only one of each is needed to wire the circuit. The other posts can be wired in parallel to create a second circuit with 12v and twice the amperage. :shock: Treat it with respect! Amperage is what curls your hair or can even kill you! (2 batteries capable of 750 peak cranking amps each can put out 1500 in parallel! Beware and use fuses to protect your accessories.) I plan to set this up soon to power 12v accessories and possibly a winch, on heavy cables. The cost is minimal for wires fuses/breakers and a secondary box to mount it all into.

A different trailer lighting/wiring sol'n: Create an intermediate Y shaped wiring harness with the European plug on one end and 2 plug ins attached to each wire at the other end. Now if you plug in a trailer with 24v bulbs or LEDs, which can handle the current, (most LEDs can handle 12v or 24v but double check yours) you can use the Y simply as an adapter. If you borrow a trailer or like to rent the Y comes in handy. Connect the trailer as usual and then add a second set of lights to the second leg of the Y. I like to use magnetic base towing lights for the second set. Mount the lights wherever you like, on the trailer bumper or the roof of your truck. I built my adapter for less than $20.

Just some possibilities to consider.

Cheers, Clive

No, NO, NNNOOO!!!! Connecting batteries like this is putting a dead short across them both! I don't want to see anyone getting hurt trying this, and yes, someone really will get seriously hurt if they do this (Ever seen a #4 gauge wire glow like a light bulb filament?! Or seen a battery explode and spray acid everywhere ?!) Please, please do not try this, ever!

I'm not sure I even understand why a 12v winch would be desired? Are they cheaper than 24v? I don't know.

For me, a WARN XD9000 was the right choice. Fits right. Easy to install, and strong enough to pull Paraguay out of South America.

Yes, it's very bad, this idea.

It must be that the 12V winch is less expensive. Why cheap out on something that can save the investment that you have in the pinz. If one wants to save a few hundred dollars
just don't get a winch at all. The stock vehicle does not come with one and it must be capable in that configuration,
I put a Warn 24V winch on mine because I used to go alone on my adventures and I was not capable enough in my own right to be able to get out of situations I foolishly got into.

I absolutely agree with Jim on this. You can not simultaneously use the battery's in a series and parallel configuration. Bad things would happen. For those that disagree please understand that this is Jim's field. I'm more a jack of all trades however having been trained as an aviation support electrician and having an AAS degree in electronics (that has gone largely unused) I have always been able to follow Jim's electrical related posts and have never found him to provide anything ether than excellent information. I view him to have more knowledge and experience chasing sparks than I do and often find that where I may understand what I'm dealing with Jim is better explaining things.

For high amp devices like winches your best bet is 24v. For low amp devices you can use a 24v to 12v converter (many of us use more than one) to power 12v devices.

On a side note many of Garmin's gps devices can accept 24v power, some list it in their specifications others require a little research.
