Sayed,
We all learn something every day. Newell changed the air system on the newer coaches. They no longer have an isolated air system for the slide seals, toilets, pocket doors and air door. The isolated system was designed for dry camping. Your coach has two 110V air pumps, but the second is only a back up for the main one. Your 110V air compressor services the entire coach. Therefore it becomes harder to find air leaks, because only the brake system, through check valves is isolated from the main coach air system. This info came from Jim Gehring at Newell service.
Let me know how the brake system test comes out.
Turn on your 110V air compressor and when it shuts off, shut off the switch to the 110V air compressor. How long does it take to leak down to zero on your supply gauge? When it leaks down to zero what is the reading of the two needle brake gauge?
