Air brake alarm at stop sign
Hello. I have a 1996 Monaco Dynasty and when the coach is sitting at a stop sign the psi drops to 90 and the air brake alarm goes off at 90. Is there a problem and if yes.....where is the problem? ...

Couple of problems:
The low pressure alarm should not be sounding at 90 PSI. Most are set to 60 PSI.
That 90 PSI is BELOW the cut-in PSI for your coach. Could be a substantial leak, could be a bad air governor (under $25). How long since the air dryer was last serviced-- that is another source if air problems?
Once above idle RPM does air pressure build to cut-out PSI (probably around 120 PSI)?
If so, how long before it drops to cut-in PSI and starts building again?
