Never seen a compact 500 AMP circuit breaker?
A solenoid is not rated for use with a winch. Even a 500 Amp solenoid can only handle that amount of current for a few seconds (Cranking Amps). On a hard recovery you will be running a lot of current through it for several minutes.

Huh? My winch has four of them. How does your winch switch between forward and reverse? Do you know what that black box above your winch is? I give up.
Oh, and Here's a 500a continuous:

I use a fuse and relay: https://www.jk-forum.com/forums/show...ctrical-Hookup
A 500 AMP ANL Fuse is way to much for my winch (a 250 AMP fues is perfect): https://www.jk-forum.com/forums/show...=1#post2540555

This guy was an Aero Space Engineer for about 30 years. I will follow his advice and not use a solenoid.

Yup FOUR, not one in line. It divides the current evenly through two going forward or reverse. Why do you think there are four? I talked to an Electrical Engineer here at work a while back and he said NEVER use a single solenoid in-line for the winch. With the possibility of running over 400 Amps through it when you have problems it may not disengage because of the amount of power being drawn. Power consumption would have to drop to 250 Amps or so before it will disengage if it were to get stuck closed.

Less convenient, but does the job that people here were discussing.

Thanks for the link. I also found this one while doing another search last night. It doesn't give the Continuous Amp Rating but has a surge rating of 5000 Amp's (probably only for 5 or 10 seconds though, doesn’t say). It appears to be a little bit smaller so it would be easier to mount. I would probably give them a call to find out the Continuous Amp Rating first though.
How big is the one you got?

sure you could what if all day, but if the unit is not powered up whats the draw on the line? have you ever touched the pos pole on the battery with your bare hands? did you get a shock? nope not unless you were grounded. same thing with the winch. if it aint on it wont draw power.
if you dont perform proper maintenance like check hoses and wires for faults all kinds of things can break, but were not talking about idiots here who dont do proper maintenace are we?
google yahoo or whatever you want about winch fires, i'd be surprised if anyone finds anything. they just wont do that.
(unless wirred wrong)

But, fact is a starter is not much different from a winch. Both have a big electric motor controlled by a solenoid switch. Both use a big power cable and draw amps by the hundred .
I've heard that some starter cables are protected by a fuse. Can't say that fused starter cables don't exist, but the 35 cars and trucks I've owned did not have one.
That means most rigs have their starters "wired wrong". Still, we drive these rigs every day. Of all the crap that goes wrong with vehicles, blown up electrical systems due to unprotected starter cables are way down on the list.
So, you can have the pragmatic approach: Millions of rigs run with unprotected starter and winch cables running to the battery and few fail, so why worry about it?
Or you can have the fail-safe approach: Running a power cable to the battery without protection is insane and both the battery and winch cables should be wired correctly and provided with fuse protection.
No point in having a pissing contest about it. You choose and then live with it.
