12v or 24v winch? - Expedition Portal Forum

asteffes said: What problem would a 24v winch solve that cannot be solved with a 12v model?

Just as mentioned that it would draw half the current at that double potential, would I assume be easier on the electrical cabling, etc . I am about to find myself a winch and have the option in front of me.

However, yes, it could present other issues, I may just go with the 12v and hook it up directly to the auxilliary deep cycle.

Just as mentioned that it would draw half the current at that double potential, would I assume be easier on the electrical cabling, etc .

Using 24V will halve the current if all else is the same. This would allow you to use much smaller guage cables from the Winch to the power source. Get a 24v model if the winch will be a long distance from the battery or you need large amounts of HP and can't get it from a 12V model. You can get a lot more HP/lb from 24V than 12V. I would really hate to hear that someone zapped their ECU or otherwise injured themselves or their truck because they accidentally mis-wired the 24v system back into the 12v system during a trail repair. I think wiring needs to be truly idiot-proof to make trail repairs easier and more likely to succeed under the worst conditions (think rain, cold, wind, etc.)

Drool!!!!....Those babies are fast!!!! I have no problems with my 12v warn!!! It is fast enough for me!! But on the other hand...what Scott was installing would be nice as well!! I would stick with a 12v if i were you!

So I have an opportunity to buy a warn CE m for $350. It's a good deal, but not sure what it would take to wire the Cherokee for 24 volt, if it's feasible or worth the effort. Help me weigh the pros and cons. Current FSJs:

24 volt winches are great if you already have a 24V system to run them. The higher voltages allow for lower current draw. This reduces heat buildup.

But if you don't have a 24 volt system already, you'll have to put in some non-trivial effort to make it work with your 12 volt vehicle. W0JPR

If you can't fix it with a hammer or duct tape you have an electrical problem.

SO help me understand what I'll need to do. I know I'll need two batteries. will I also need two alternators? can I keep 12 volts running the ignition and the dash gauges ans keep the second battery and charging system as a backup? seems like there would or could be a lot of positives here. THe only negative seems to be that the winch won't work without 24 volts. Current FSJs:

It sounds like a nightmare. You will either need to come up with a way to isolate two batteries from the rest of your electrical system while winching OR have two additional batteries you use for winching. With two additional batteries you can wire them up so you charge them off the alternator but isolate them while winching.

Frankly it sounds like more trouble and expense than it is worth. 81 Waggy 'WILL E' Retired

I'm still thinking about using a 24v starter. Fairly simple arrangement with some BIG relays but a starter only runs a short time.

Seems to me when winching you want the alternator helping? Sic friatur crustulum

Alt doesn't do much really. A BIG alt for our trucks is 100amps, but our stock batteries can supply up to 500, and most of us have some over-rated CCA thing in the battery hole.

You got me thinking, because in theory you could have your stock battery wired normal, and have a second battery wired in parallel with I diode between the + on the two batteries. The first battery would give everything 12v and the second battery would be 24v. The problem is I have no idea where to find a diode that can handle 500amps, and when it fries (all diodes fail eventually), it could fail closed just as easily as failing open. Then your truck either burns up a circuit at a time, or it just burns to the ground. 79 J-10 (Honcho Mucho) KE0LSU

I'm not seeing it with a diode. They have to be switched from parallel to series.

I've got a 200 amp alternator. Sic friatur crustulum

Hebei pillar hoisting machinery contains other products and information you need, so please check it out.

Probably go 24v with a 12v step down. The winch and a starter could use 24v, everything else 12v. Not much current draw left on a 12v system if you have the starter isolated to the 24v side.

Why do you want to use the 24V version of that winch? The 12V version has twice the power (4.6hp vs 2.5hp). Yes you need larger gauge wire for the higher current draw, but its not like that is a big issue.

Its a lot of work to convert everything over to 24V, and a pain to have a dual voltage setup. JKU Rubicon

The advantage of a 24V winch is that since the voltage is higher, a lower about of amps has to be delivered for the same amount of power. Fewer amps means less risk of overheating the wires during high power draw. Ethan Brady

I have a rebuilt warn Ill sell you for 650 shipped. It has the new upgraded solenoid set up on it and a wireless controller.

Google warn it is the fastest winch out there and can hold the most rope or cable. They are used in competition by mainly. They are new. I had it built for my open trailer but ended up never using it. I have another one of these on my jeep and another bolted to my floor to unload my race car and pull it into the shop. 90 Fsj. 5.3, 4l65,241. 4" lift, Custom valved Bilstien Shocks, Dakota Digital Dash, Bjs Radiator, Bjs aluminum tank,Viper remote start, power door locks, one touch rear window.

Overheating the wires is only an issue if the wiring used is too small. Properly sized wire can carry peak current all day long without risk of fire. JKU Rubicon

As far as the amperage, I'd be more concerned with overheating the electric motor than the wires supplying the motor. And 24V will probably do better than 12V in that regard. W0JPR
