@Taco2Cruiser thanks. I'm paranoid, I guess. Would you consider a battery cutoff switch, or do you just run your wiring within a wire loom to protect it?
No it’s good to take these extra steps to protect your investment and your family inside it.
Wire the positive and negative 0 gauge power leads directly to the starting battery. All wiring is already in its insulation and attached the same way as the factory wiring. Does your factory exposed leads on the battery terminals catch fire? Because they are designed that way. The control box is no different.
I would not consider a battery cutoff because what would it provide?
Let’s say you have a front end collision, and it is so bad that it damages the winch control box to cause spooling. Even under that rare worse case secenario, what’s it going to hurt? The bumper is destroyed, along with your truck. Are you going to try prying whatever hood is left open to turn a cutoff switch? The wiring will be too thick to put a cut off inside the cab reliably without major cuts in the firewall. Or are you going to get your family out of the carnage and away to safety? A spoooing winch will only destroy the mounting bracket its attached to, it won’t cause fires. I’ve seen two guys hands get sucked into a winch drum. Both were because of lack of training, not a connection becoming active.
It’s like when a guy told me I should have a lock on my onboard water tank, because if I roll the truck, I’ll get water in my cab. I responded with, “if my truck is rolled over, then my headliner is destroyed anyway... because my roof is caved in.” I think we need to think about if something does go bad, then why does it go bad, now in that situation, what now matters? That’s not to mean “oh nothing matters anymore.” It means that when bad stuff happens, priorities of work must start, and what is your priorities that will make a difference and what tasks don’t really help the situation.
The safest thing you can do with a winch is to wire it the way Warn says, and don’t mess with it! They are much smarter than all of us. Then get proper training instructions. Not trying to act big or anything, but I’ve done too many vehicle recoveries, with armored gun trucks, under gun fire, from mountains to cities. The principles are simple, but must be followed to a T.
Leave your winch control switch unplugged from you control box until your winch line is set and you are ready to pull. Don’t let other people control your winch, you control the driving of the truck and your winch. Spotters give recommendations, but drivers are always in control. When spooling the winch back in, keep your hand a full body length away from the fair lead. And take your time, don’t let bystandards comments and body language make you rush to failure.
Do that, and you’ll be safer than you’ve ever been. Because you have self recovery capabilities, and are safe to use them.
Sorry to go from wiring to training. Maybe it’s becuse this falls into what I do this for a living, but I just feel when someone asks about messing with these things, it’s important to view all aspects.
