ARB air leak
One of the blue lines apparently got too close to the exhaust (while Molly was driving :rolleyes: ) and melted through. No biggie - my question is though, the compressor never reaches pressure and shuts off. But if the solenoid is closed, the broken line shouldn't matter, right? Do I have a bad solenoid too?

You could have a burned up valve on the pump.. ARB pump? Mine went out and all it does is run and run.....
Take the solenoid out and plug the hole... if it fixes it there is your problem.. if it doesnt.... i would send the pump to ARB for fixin...

I would consider sending it to ARB first, might get fixed for free... they have reapaired mine twice at no cost...

Fix the blue line first...then see what happens. ARB has a new "mini" compressor too and there are other options.
I prefer a 100% duty cycle compressor and an air tank to the little ARB compressors...I can fill up the tank once in the morning and wheel all day and the compressor might come on once...and that is cycling the lockers quite a bit.

ARBs and leaks are all about the competence of the installer, unless you break an axle shaft or something and damage the inner workings of the ARB...seen that happen on a buddies' Heep at work...busted something inside the ARB and had to send it back, but they did fix it for free.

Keep in mind, the QD would only be for filling tires, and I would never be using the compressor to do both jobs at once (run locker and fill tires).
Is this doable? Sorry if this is the wrong place to post this, I don't mean to thread-jack.

So, can you run an ARB locker(s) off of a Viair 400c with no auxilliary tank? I was thinking of just making a mult-port manifold (as opposed to a tank) and connecting a pressure switch, both locker lines, and a quick disconnect to those ports.

OK, I'm a dumbass. My new bumper is fitted for air storage:
The "outlet" fitting on top got snow packed in it the other day and must have gotten stuck in the "open" position, and leaked enough that I didn't really hear it. I put some tape over the top to keep any snow out, and that allowed me to hear it leaking. Fixed the coupler, and the compressor shuts off as it should now.
Sporticus:
You can use any compressor (or even CO2) to run the ARB's, but you have to be VERY careful about the pressure. Don't exceed 90psi or you risk blowing out the seals in the diff. The tank is still a REALLY good idea. Here's a compressor that looks VERY interesting for our applications:

3CFM could probably run air tools for short periods with the tank...

^ Thanks, guys.
I already have the Viair. Just trying to build around it and do it correctly.
So, TC, you are saying I should use a regulator on the ARB line in conjunction with an 85/105psi pressure switch (I alrady have the PS, too) on the tank b/c 105psi will be too much for the seals?
Is there a fixed (non-adjustable) in-line regulator for ARB use (85-90psi)? Something nice and small?

I thought they were like 70/85 ... but could be wrong. Personally, I don't think it's worth risking it. You could call ARB - bet they could tell you exactly. Supposedly they have good customer service - never needed it myself though.

Tim was the best guy at ARB, he left.
I am pretty decent.
The compressor turns on at 75 PSI or lower and off at 100 when I was investigating.
This is why just blasting most shop air into the locker to pressure test is really a great idea.
Good luck.

I have a 105 psi pressure switch on my air tank that feeds my manifold for my ARBs...no problems.

Guess I was mistaken - thanks for the clarification guys. (My experience was based on someone using CO2, and not being even close - like 200psi or something stupid)

I think that there is a safety margin built in.
If 100 is good, 150 is not half again as good.
The ARB compressor is made for tires. You want more air, get CO2.
Many fine ARB's have given their lives airing up tires more than 28's.
