Well, I got home and went out to fire up the beast, the seals were completely deflated and the door didn't even think about opening. Supply air was at 0 and the brake airs were at probably 5 or 10. Fired her up and idled for 5 minutes, all pressures were at about 45 so I raised it up to 14 or 15 hundred, another 5 minutes and the pressures were at 60 to 65. shut it down and supply pressure fell within a minute or so, experience has shown the brake pressures won't be down till tomorrow morning. The pressure increase across the 10 minute seemed pretty linear, slowing a little in the second as the pressure rose. Not sure it wouldn't have continued a similar rise at idle. Hooked it to the compressor in my garage which puts out 7 CFM at those pressures and managed to bring the supply pressure up to about 50 PSI but that's as far as it would go. Took a turn around the rv and the only sound to be heard was the air passing through the quick connect at the service port, even using the inficon. Unplugged the hose and the pressure at the supply gauge again fell within a minute or two.
