Spartan MH-2242 Air System Diagram
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.
