Birchy, I have an '01 CTD auto w/ AD II, mounted on the frame. Installed about a year ago, it was supposed to control at 15 psi but had 5-8 psi initially, per my MaxTow gauge w/snubber and electronic sender. After several weeks of worrying, I screwed the adjuster in 2-3 turns with very little improvement. I took the relief valve adjuster out and found the spring inside was very flimsy. It would not apply enough force to the sliding piston in the relief valve to build that pressure; if the adjuster was screwed all the way in, the adjuster stem could push against the sliding part of the valve and create a fixed orifice which could REALLY raise the pressure,which is NOT good, could over-pressure the PV45 injector pump and kill it. Contacted AirDog- they sent a replacement spring that holds the relief valve in but it was for the old AirDog and wouldn't fit- diameter too large . Checked with them again and they sent a different spring, stiffer than the original and the right diameter. I replaced the flimsy one with this, and then was able to easily adjust the pressure to 16-17 psi, or anything else i wanted it to be. Just saying- the pressure adjuster on the Raptor looks the same externally as my AirDog II, so perhaps yours has the wrong spring; the ID on the bag the good spring came in is:"1V-00034: spring, 71906s A/D II 15psi". Their parts line is 317-421-3180. This may help.

What brand anti-freeze did you put in?

panzerq- On my '01 Ram CTD, I installed a Glo-Shift FP guage downstream of recently-installed Airdog 100. In conversating w/ Mfg re: troubleshooting, they mentioned that the guage itself gets 12vdc for powering the logic, then reduces that to 5vdc which is the source to the sensor on two wires. The sensor then sends a variable signal on a third wire, depending on sensed pressure, back to the guage which interprets this signal as a pressure. Just sayin- maybe don't look for12vdc at the sensor. Check with mfg. to find out a range of volts (sensor output) on which? wires at the sensor while operating. Also maybe install a plugged pipe tee between the snubber and the sensor where you can screw in a mechanical guage to verify pressure, then remove the guage and replug the tee afterward. Also, check to see if the splice joints are soldered.This could correct any twisted-wire problems- poor connections will do worse on lower voltage.

I replaced the PS pump 2 years ago in my '01 CTD because of the 'groaning' ONLY WHILE TURNING the steering wheel to the right. The replacement pump had no effect on the groan- it has continued to this day. Does the box have a relief valve, or does it take a little more pressure to turn right?

The Britebox kit from Geno's Garage is what I put on my '01 2500 CTD. Nothing easier, works great, PLENTY of light now.
