Spartan MH-2242 Air System Diagram

Hello,
I am looking to find the air system diagram for a 1992 American Eagle. I called Spartan and they stated that they didn't have it??

I am having trouble with the suspension air dropping slowly while traveling. It does not drop if stationary, but does drop slowly on curvy or bumpy roads. If allowed it will go down until the air pressure warning light comes on. I have to brake several times to get the brake air pressure to drop enough to cycle the compressor. Once back up will stay for as little as 20 minutes up to an hour depending of the road conditions. I am thinking that it is a Pressure Protection valve but need to see how many and where to get to the correct one.

Thanks,
David

I agree locating the source is the first step. How long since the air dryer assy. has been serviced? That is the most common cause of air pressure problems. It tells the air governor what to do-so to speak.


I have the air system in pdf form but can't seem to upload it tonight.

Hello Ray
It’s been a while for sure and most likely never. I will service the dryer and see if it helps. Sorry so long to reply but never knew anyone had replied. Thanks for the drawing

Thank you for you service,

Thanks
David
