Unsafe Locking - Randy’s Electrical CornerPosted in How To: Electrical on January 17, 2014
You Jeep guys teach me more and more things every day. When I first started writing for Jp, I thought a locker was a smelly thing at the gym or that dusty place I put my books in the first day of school and never looked at again. You can imagine how confused I was when I first heard one of you guys say “air locker.”
Of course, when I first heard it I couldn’t ask what it was or everyone would have laughed at me. I was on a wheeling trip with one of the other editors and one of the guys was trying to get his Jeep to climb a waterfall when I heard him say, “My air lockers aren’t working,” which confused me. I mean, what kind of air is so expensive you have to keep it in a locker? And how do you keep the expensive air in the locker from coming out through those little vents? Is that what he meant by his air lockers weren’t working? I eventually figured it out, but booooy was I confused for a while there.
Now I know what an air locker is, and I really like them. As you all know, the most popular air locker is the ARB Air Locker. The only thing I don’t like about the ARB Air Locker is the way that they have you wiring it up. I mean, OK, I get it, having the front locker come on when you are on the highway is dangerous and the company is just trying to cover its butt, but sometimes you want to have the front locker on and the rear locker off. The company also has you wire the compressor up to your ignition, which is great if all you use the compressor for is the air lockers. But if you use it for filling tires, it’s not the best way to go.
I mean, I’m not a huge experienced Jeeper, but I’ve helped enough Jeepers air back up that I know I don’t like breathing exhaust while I’m doing it. If I had the choice, I’d wire the compressor up so that it can come on even when the Jeep is off. I’ve filled 35s up from 5 to 30 psi with the ARB compressor and the Jeep still starts afterwards, so that isn’t a problem. So, I went and dove into the ARB wiring schematic and played with some stuff so I could show you a different way of wiring up the compressor and lockers to be a little more useful in real world situations. Mind you, ARB doesn’t suggest that you do it this way.
