My original problem was coach #375 was not building air pressure, running on fast idle for 40 minutes it would only build up to 75 psi on the brake gauge and 75 psi on the supply. Most everyone said it was the air governor. After a monumental task of getting the old governor off, which had to be cut off in pieces, I managed to relocate the new air governor to the fire wall in the right rear engine compartment. When I started the coach up, fast idle for 40 minutes and the air pressure built up to 75 psi in both brake and supply. When I shut the coach off, I watched the supply gauge drop to 0 psi, within a minute, the brake supply gauge is holding at 73 psi. I didn't hear any air leakingor sissing, and I have sprayed every fitting I could find with soapy water and no leaks. During my investigation my brake supply tank was about 1/3 full of water. I drained that and installed a new remote drain valve. I also found a tank welded into the cross member in the rear and drained that one. I found the air tank in the right tag axle wheel well and drained that one as well. Does anyone know what I should check now? The guys at Newell weren't any help.

Thanks,

Jeff
