Trailer Winch Wiring

[N80]

To the lad who wants to pull a race car with a 3400# ATV winch, realizes that 3400# is on the first roll of the cable on the winch drum.Just a thought, don't know if you knew that or not.

Most 3400 pound winches will pull a 3500# car up a trailer ramp with ease. Rolling load, small incline.

I cancelled my eTrailer order. Went to Northern Tool and bought a Warn 4000# utility winch. Ordered a cheap wireless remote from Amazon that I will wire into the solenoid. I ended up spending about $75 more dollars but probably got a better winch than the eTrailer "Bulldog". The remote from eTrailer looked better and was plug-in-play but twice as much as the Amazon one. All of this stuff, including the Warn, is made in China.

Going to get my trailer so I can install the ingenious bolt-on removable mount that I referred to earlier. If it works, I am brilliant. But, I've felt brilliant before many projects that I felt like an idiot after the project. We'll see. Will post results in a separate thread.

I will order cable and such on my truck once I get the winch installed.

One of the big differences in the Warn vs the eTrailer Bulldog winch is amp draw. The Bulldog winch draws #350 amps at maximum load. The Warn draws #140 amps at maximum load. Granted, the Warn is rated at 4000# and the Bulldog is rated at 4400# but that is a big difference in maximum amp draw. I think I will be fine with 4 AWG cable and a 200 amp fuse.

Okay, here is my little bolt-on solution for a removable winch mount. It required two parts from Northern Tool. The first part is a box hitch receiver made to bolt on the underside of a step bumper. It is a fairly beefy part. The second part is a pintle hitch adapter that fits in a box receiver. It is very beefy; too much so in fact. The shaft is solid steel and it is heavy and makes the whole winch assembly heavy when moving it. Both parts are shown here and cost about $65:



My trailer has a fairly thick , 6" high panel across the front. I drilled holes and mounted the hitch receiver facing up as shown:



The pintle adapter just drops down into the hitch receiver. The winch will be mounted on the pintle plate:



Here is the whole thing in place. Works really well and when the winch is removed there is nothing on my trailer deck and nothing in the way. Winch can be locked in my toolbox or a locking hitch pin can make it secure when in place.



Problems: 1) Ruined a handful of cheap drill bits drilling through the thick pintle plate and took a good 30-40 minutes. No big deal. 2) Pintle adapter is heavy and makes the whole thing heavy. 3) There is still no way to hook the thing up to my truck hitch receiver since it would be oriented wrong if I used the pintle adapter shaft. I will solve this problem with a hitch mount made for winches. It will mount between the winch and the pintle plate. It will have handles (which will help with the awkwardness and a hitch shaft that projects rearward, about $50.

A lot of trouble and expense but it keeps the winch off my trailer deck, makes it removable and able to use it on the back of my truck as well. If I had welding capability Icould have fab'ed up something cheaper but probably not as neat.

Wireless remote arrives tomorrow.

Will put wiring harness in truck sometime next week. Total project about $500.

The winch's max draw is 350 amps.

I read through this jumbled mess up until this point. Post #38. Four pages to get to the first mention that I could find of the most important fact that needs to be known before any talk of wire size makes any sense.

Until you know the current draw (amperage) and the length of the conductor, you have no businesss talking about wire size.

Once you have that, you can look up tables that will tell you the correct wire size. There's no room for, "I think this should work....".


N80, the reason you have gotten so much conflicting information (as you mentioned), is that most people are in the same boat as you - they don't understand electricity. Nothing wrong with that - we can't all be experts at everything. The problem comes in when people who have no understanding start throwing around uneducated opinions. "I did it this way!" "Some guy told me to do it that way!"

I didn't see how this discussion finally wound up, but I'll just comment on the fuse issue. If you are sure that you can smell the smoke, get to the hood release latch, release it, pop the hood, and throw the disconnect switch before a fire starts, go ahead and use a disconnect switch instead of a fuse. On the other hand, if you are mortal and you don't live in a perfect world where everything always goes right, go with the fuse. 400 amps, not 350. You want some headroom for what is called, "inrush current".

That's the point of a thread like this. I started knowing nothing at all about how to do this. Now I've got a pretty good idea.

Well, sort of. The tables I was able to find say very little about duty cycles etc. so they don't really address the actual application all that well. Granted, they would lead you to larger wire sizes, but that can be unnecessary and pretty expensive too.

Its usually not that hard to sort out the good advice. And sometimes it can be harder to sort out the overkill advice.

It hasn't wound up yet because I'm not done. It has been my intent to put a fuse in. Not 400 or 350 in the case of this winch since max draw is less than 200. If I do a switch it will be in addition to the fuse but I probably won't.

Just talked to a buddy this evening who is a welder and just installed a (similar) winch on his vehicle. He told me about a local welding shop (that I was not aware of) with better wire prices (good, flexible, all copper) than what I'm seeing on the internet. I'll head over there next week.

Forget duty cycles. Pay attention to voltage drop.

Earlier you said it was 350. ??



A welder is probably a great bet for wire at cut rates. Just in case, though, compare them against BestBoatWire.com. Good stuff.

Different winch. But I quoted the wrong specs for the winch I actually bought. Max amp draw is 250. Still, better than 350 of the first winch I was considering.

This puts me back in the 2 AWG wire range rather than 4. About $75 bucks on Amazon with ring connectors included.

Thanks I'll check them out.

I have found that most of the off brand winches made in china have higher amp draws than the name brand winches made in china. I think you are ahead buying the warn over the E trailer off brand .
I can't remember the size welding cable I used. I have been able remove it when I've traded trucks and install it on others.

Get another piece of 2" receiver tube.
Remove the winch from the plate its currently on.
Weld the 2" receiver tube to that plate in the same orientation as the one on your truck.
Use the winch mount for receivers that you are going to get, and mount the winch to it.
Now you can use it in your truck, or on the trailer adapter, and it will always be in the correct orientation, and you can remove the stand from the trailer when not needed, as you wish.

Make sense?

I just welded a tube to my trailer last fall so a friend could use a portable winch mount on my trailer. I have a 6" high bumper bar across the front of my trailer, so I welded it to the top of that and put a brace under it to keep the bumper from bending when pulling.

Okay, so go with a 300 amp fuse, and you'll be good. You never want to size your fuse for the maximum draw, you need some headroom.

Here is my setup. All of my standard jumper cables are 1 gauge CCA or solid copper 25' in length, with Anderson type QDs on both ends. My truck and Jeep batteries also have mating QDs and winches mounted. And the jumper cable alligator jaws also have QDs. Very flexible setups.

My 20+2 equipment trailer has a 9k# winch in a portable mount. The winch was used recently used to pull an old Ford tractor with low/flat tires that had been sitting in a field for quite awhile. Lots of physical resistance that really tested the 9k# winch setup. Less capable winches would be okay for ideal situations with a rolling load on a hard surface.

I welded a truck step bumper 2" 5000# receiver to the trailer's front structural assembly. I would not consider using less than 2 gauge battery cable and 0 gauge would be better as the available voltage drops the longer the cable is due to wire resistance. And for the most part, the larger the cable diameter the less resistance to current flow.

Added photos of tractor/winch setup. All the same wiring principle.
