24v Warn winch into a 12v Terrano

[marmel]

I have an oppurtunity to purchase a 8000lb warn winch at a decent price.

I want to put it into my Nissan Terrano which of course is 12V.

What is the easiest way to go about this?

I guess the options are to swap motor for 12v unit from someone running a 24v truck, purchase another 12v motor (expensive) or is it possible to add another battery just to run the winch?

longer term it would be better to try and find someone to swap motors so you can run it on 12v, it would be a lot of shagging around to try and link 2 batteries together to get 24v and still charge them individually at 12v

If the winch is a good price grab it and sit on it for a while and you'll eventually find someone that wants to swap their 12v motor for a 24v one

Will the solenoids still work with 12v?

good point .... I
have had a look on the warn website and is seems that they use the same solenoid pack but wire it differently

So from that I would think that Sadam_Husain's idea would be best

had a talk with an auto sparky about this because my truck is 12v but the 24v winches are typically faster. He said it's easy enough to do running two batteries and sending 24 to the winch and 12 to the rest of the truck. He did mention a couple of things that you need to get to make it work properly obviously its not as simple as just throwing in another battery but it can be done. He was talking about the option of running another alternator as well which I like because then I onlu need one of them working to drive home instead of changing the bastards on track.

If you are serious about doing it have a chat to an auto sparky and if you can't find a decent one that knows about trucks and 24/12v circuits let me know.

I have a warn 8274 24 volt winch that I bought for the faster line speed under load compared to the 12 volt. My plan is to fit it to my YN60 surf (12 volts and petrol). I have got all the gear together to fit it and run it all but haven't done it yet. But here is my plan.

Remove the 12 volt surf alt. Mount 24 volt land cruiser alt in new position, higher up on the engine so it is out of the crap.

Mount two extra batteries wired in series (24 volts) and the alt charges these at 24 volts.

Because mine is a petrol engine I wanted an electrical source completely separate from the winching batteries to run the ign. So I have a step down transformer that steps the 24 volts down to 12 volts and supplies the unmodified original truck electrical system including the original starting battery.

I also thought that because the 24 volt land cruiser alt is from a diesel it still has the vacuum pump on the rear of it. I will retain the vacuum pump and plumb it so it is suppling a positive air pressure into the distributor.

Hope that helps.

I couldn't get the 24v Warn solenoid pack i have to work on 12v, works sweet with 24v.

Connecting a 70amp odd 12v starter motor to one battery in a 24v system is a real quick way to kill both your battery's, and a 30amp reducers are expensive enough as it is, let alone a 100amp odd one.

my plan was to run a second alternator and twin batterys just for the 24v winch system and leave the truck 12v alone, but ended up waiting and watching until a reasonably priced 12v winch came up. less hassle in the long run

Also factor the cost of a strip down and re-build / possible replace of parts into the equation as any 2nd hand winch is going to need some love.

Motors from the runva winchs bolt straight on. I had a thread on it somwhere on here. Did it last year so I could compete in the Reefton challenge.

Using a 24v to 12v supply to run a truck is very unreliable. If you want 12v and 24v, then the most reliable is two complete seperate systems.
My old truck had the standard 12v 110amp alternator that charged a 925cca battery to run the truck and a 70amp 24v that charged 2 x 25 plate blateries just for the winch. This proved to be extremely reliable and meant there was no dramas powering the 8274 with twin 7.8hp Superduty motors.
That setup is a little extreme but i simplier version with 3 normal batteries is still the best way to do it.
The other way I know works is running a 24v alternator with your 12v power taken directly off the batteries indivually and using an evencharge to ballance the batteries and stop them dying.
Other than that I don't know of anyway of doing it that will be RELIABLE. Yes it might work, but for how long is another story.
