2004 madp 4302

I have a 2004 Mountain Aire MADP 4302 Spartan chassis and tag axle. The air pressure for brakes and suspension was working fine a month ago. Now the air pressure will not come up. The gauges are all the way down. I can hear a little bit of air underneath the front of the coach, but does not seem like enough to prevent the gauges from coming up.

Any ideas for what might be wrong?

Do you know where the governor and or air dryer might be?

There should be no air leakage while the system is airing up , and if the leak is in the air suspension the tanks should still build to 65 PSI , That's enough to release the park brake .

Contact " Spartan Motor Home Support " ( they don't charge for info ) with your chassis serial number and ask for an air system diagram . They will be able to answer your other questions on , air dryer and governor locations .

Air dryer is in the battery compartment, passenger side rear, under a plastic panel.
