Powering a electric winch

Thanks PastorCharlie. But my setup is a mobile which in a cradle for using on front or in rear tow bar, A Sherpa Stead rated at 17500l lbit only weighs in at a bout 60-70lb and will live in toolbox in rear of truck until I may have to use, I also have snatch blocks sand boards etc, the boards will be first go to , the the winch if this is not sufficient, as we travel alone and sometimes in som remote places, and has been bogged from time to time in sand or slippery mud, rather fit which on rear if best way to get out.

It takes a full 20 minutes of rest for a standard winch motor to cool-down. Between 70F and 300F the motor will lose 30% of its pulling power.

A snatch block can easily double line pull speed when a straight pull overloads the winch motor. With little load a snatch block will halve line pull FPM. But be careful with overloading.

If the wench is properly mounted to the front frame there is no need to move it to rear for a rear pull.. Use snatch blocks and if the needed pull is directly the vehicle with the wench use a snatch block out to front of vehicle and thread wench cable through it and pull it under vehicle to rear for pulling. If the need pull is off to the rear side of the vehicle with the wench use a snatch off to the front side of the vehicle with the wench thread the wench cable through it to the vehicle needing to be towed at rear side. Snatch blacks are very helpful in maximizing pulling options, each snatch block used multiples the force of the pull.

My wench is very heavy constructed and weigh between 100-200 lbs. Lot of weigh to be moving around and requires lots of secure mounting. 12,000 LB. WARN WENCH

Thanks Josh yes I know that Mex knows his stuff with electric, and he suggested to upgrade the negative cables and run 00 to the rear, and that is what I intend to do and also run a oo cable between the positives with a 300A fuse at each battery before cutout switch to winch.

Frank,

Mex really knows his stuff.
I have a 2019 350 Diesel.
There are two batteries, 12 volts in parallel. the Negatives are to the frame and the positives are cross connected together forming one larger 12volt battery.

I've been looking into replacing both of my grounds because they appear to be undersized for the load I'm placing on the cables (number of amps observed when cranking is right at the upper limit for the size of the cables).

if you want to use the ground of the chassis - make sure both of your existing cables are in excellent shape - are clean, and there's no corrosion. Slather them with silicone grease to insure no corrosion.

You'll need to run 1 00 cable to the location of the winch with an inline fuse rated at 430amps (or as close to it you can get).

You'll probably get better performance if you run both a positive and negative cable - but it'll work using the frame as a ground.

I am setting op winch so can be used front and rear. Has been advised to use 00 cable to run to rear of truck, so either I run to cables +and- or I use chassis to run from rear to front and only run + to rear and short cable from chassis, I have also been told to upgrade. the - to chassis of both batteries, I also planned on connecting the 2 + together with a oo cable, only plan on connecting winch to one battery true the 500A breaker supplied with the winch. By the way my truck is a 2015

Its been said.

Connect to the "other" battery. The wire connecting the two 12 volt batteries is plenty big to carry current.
Ground? For what? connect to pos and neg terminals, and use a circuit breaker, which should have come with winch.

Diesels have two batteries, yes for cranking power, but also for glo-plugs if it has that, which draw a lot of power. I have forgotten what year truck you have by now.

Do not try to connect a pos to one battery and a neg to the other battery, it will work, but you will be a laughing stock at the mud bog.

Getting ready to do the wiring as hoping to have winch next week. My Ford workshop recommended that I only run the 02 active to rear and use chassis as ground , while also adding larger ground from each battery to chassis, what do you think.
Thanks Frank.

2 6V batteries configured for 12V or 2 12V setup for 12V?
If 2 6's you MUST use both to power the 12V winch (an assumption). If 2 12V you "could" wire to only one battery but that would still not be the recommended setup.

He stated that it was a diesel. It will have two 12vdc batteries connected in a parallel configuration.

Some premium grade group 65 batteries have almost 900 CCA. That and a custom mount 200 amp alternator can drag a vehicle a long way through sand or snow. Winch manufacturers could use a 15 HP ND gear reduction big rig motors on their largest winches I wonder if that's not the case here?
