If my wife wasn't about to pop out a baby in the next few days I could probably get up that way. I think you're just an hour or so from me.

How did you do the blue lights? Blue lens caps, Clear caps with blue LED lights?

Glad you're okay. If you get an air hose and glad hand, you can air down the tires to try and get out then refill them from on-board air.

No one's rebuilt or replaced their PSAC? Kinda glad I'm taking pictures as I go then. Might be useful info.

My power steering assist cylinder (PSAC) was leaking so I'm tearing it down and replacing the seals. I'm waiting on new felt pads and dust shields, so I've been reading up on reinstallation. The only part I'm a little confused about is the travel adjustment. The TM states that when properly...

I'm actually leaning towards the Kleinn 401 now. http://www.kleinn.com/Roof_Mount_Truck_Horns/Dual_Roof_Mount_Truck_Horn_401.htm Sound: http://www.kleinn.com/sound/401.mp3

Does that run all 3 horns or just the Kleinn? I saw the Kleinn 401 dual horns on their website. I might remove my horns and replace them with those. I think they might fit.

That is a perfect tone. If I can't tune my horns a little lower, I'm getting the Kleinn!

Yup, I was right. They're selling it for $200. Did you really give it to them for free? If so they're making a nice profit.

I might have issues with that one as well. I'm thinking of adding an in-line pressure gauge to see what's going on.

For the pressure transducer off the wet tank, you can disconnect the plug from the CTIS harness and short the pins. That will trick the CTIS controller into thinking there's 120psi in the tank.

I just cranked the outer mirror arms more forward and angled the mirrors back. The doors don't hit then. You could also add some washers to the door stop that's already in the door frame.

Here's a write up: http://www.steelsoldiers.com/showthread.php?137569-M939A2-CTIS-PCU-solenoid-replacement&p=1693141

I got a few requests for this info so here goes. My CTIS was doing 5 blinking lights after reaching 120 psi and there were no noises coming from the PCU on the floor. The troubleshooting guide pointed me in the direction of the control solenoids. To test f this is your issue, disconnect the 6...

That deserves it's own thread. Let me look through the invoices and do a write up. I forgot to take pictures, but it's pretty straightforward.

No. It was the driver side front. I found that 2 of the 3 solenoids were dead in the PCU, so the ctis was never actually coming on and filling. Once those were replaced the ctis would come on, but once the truck was shut down the front driver tire would deflate to 20 psi or so before the wheel...

If they still have it I'd pick it up in person! But having got it for free, they'll probably sell it for $200. Gonna call them tomorrow and see. Maybe I'll get lucky.

Unplugging it is not an option. It must work. Such is my nature. So, I should get out the soapy water and check all the lines and connections from the PCU to the QRVs and from the QRVs to the wheels. Basically everything between the PCU and wheel valves. Would enough small leaks on the fill...

Reading through the ctis troubleshooting guide, it seems that air should not come out the qrv at all except during a deflate. I would imagine as the system inflates, if one of the 3 axles is at pressure before the others, air would be released at that valve. Is that the case or not?

Some things to note: 1. The o-ring that seals the connection to the tire stem is worth replacing. I did not but will do so later. 2. The steel tube coming from the hub that attaches to the wheel valve is actually 2 pieces. I cleaned the rust out of the connection with steel wool. There was a...
