Thanks Guys,
For the timely responses, I should have mentioned that this problem occurs while the Coach is operating @ 110 – 120 psi (which caused a great deal of panic the first time!)

Richard, good call on the Pressure Switch being located on the Primary Air Tank, I’ll check tomorrow. I’m pretty confident that location will be correct, (don’t know why it didn’t occur to me!) Your guys are awesome!!

Michael, on our last Coach, we once blew an air line apart in Gallup, Nm. & had just a few seconds to respond after the Cruise Control suddenly turned off (Non DDEC) before going into E-Brake lock-up. Your description of the Air Pressure indications & sequence of events are spot-on.

Wally, I recently renovated the Auxiliary Air Compressor and Compartment (still needs to be sound proofed with Dynamat) on Show 488, the Air Compressor is mounted in the compartment behind the Right Front tire, it never ceases to amaze me that these Coaches can offer so many different variants.

Clarke, Your coaches air system sounds like it very tight indeed!!
Again, thanks guys for all the great help. Will post the results.
