Ok, I've been doing some playing around trying to understand how the air system works, if I have any leaks, and etc.
Yesterday, I aired up the suspension using my garage compressor to 110 psi without retracting the jacks and let it set overnight. By this afternoon, the green needle was at 0 psi and the yellow at 40 psi. What was interesting is that the front suspension was back sitting on the jack but the rear is still at ride height.
So, I suspect there is a leak somewhere in either the front suspension or brake lines. It looks like the front and the rear are isolated but that there must be some kind of a pressure regulator between the two tank, which allows both to fill from a single source, but doesn't let the one tank (yellow) completely loose pressure if the green tank does.
This also suggests that it doesn't take much pressure to fully inflate the air bags....seems that it reached ride height by the time I got to 60 psi or so. Is this a valid observation??? If it is, could one soften the ride by reducing the air pressure on the bags??
Regarding air leaks, how long should it hold pressure in a static condition??
If anyone can shed addtional light on our air system, it would be greatfully recieved. I been trying to find a plumbing diagram for a Magnum Chassis without any success.
