PW winch wiring question

[flan]

I’m wiring my winch and would like it fused at the battery for many reasons. I’d imagine the factory winch is fused somehow, anyone got a idea of where ram pulled the positive feed from?

 

[Darkone]

I would imagine using the buss bar on the driverside battery. Mine came with a spare 250amp z case fuse on a stud with a nut holding it down. Unless you want a resettable fuse like a busman or blue sea. Then I would just wire direct to the battery through your fuse then to your winch

I looked at that briefly yesterday and the thought did cross my mind. I researched the M12’s amp draw at full pull and found it to be 440 amps however.

With that kind of draw I’d wire directly to the post of the battery and use my own relay. What size gauge wire will you be using?

 

[flan]

Whatever the winch came with I didn’t look too close but maybe 2/0?

Warn always says to wire directly to battery no fuse. my pw is directly to the buss bar with no fuse or relay.

Is that buss bar fused? Darkone mentioned a 250a fuse. I’m not by my truck to look.

@flan the buss bar isn’t fused but the z case fuses slide down over the studs and give you the option to have fused power

Gotcha, thanks. Jadmt, is that the winch wire sitting on top of the fuse? I’m not familiar with this buss bar setup.

no and winch draw a lot so 250A would be insufficient in my opinion. in my photo the winch wire is on the last post (top of the photo). the wire you see with the fuse is for my ARB fridge.

Just follow the instructions that came with your winch?

I installed a winch in my last truck. Direct to the battery with no fuse.

 

[Rockcrawlindude]

I go straight to the battery with all mine. They pull LOTS of amps

This comes up in the Jeep world from time to time and there is no good reasonable way to fuse a winch just like how many starters aren't fused.

One option is putting a battery disconnect on your winch line. Marine supply shops are a good source of these.

So after research I’m going to do a flaming river 500a disconnect. Many arguments for and against, I’d already made up my mind before this post was made something was going in place.

Link? I ain’t mad at it, it’s not a bad idea

Here you are sir. I plan on mounting it on the driver side just forward of the battery.

I know some of the winches i have bought came with large circuit breakers that go on the buss bar then the positive connects to that but my warn never came with one i have to pull the contractor cover to install the wireless remote receiver i would not be surprised if there was one in there

i used a 500amp fuse for the Jeeps 8000lb winch. Been in there for over 10 years now with no issues.
