Just had this problem. Do you have air entering primary (driver side,orange) or green ( secondary-air bags fan hub and such)? Check fittings and small adjuster at air dryer next to governor. Or maybe your governor itself.

If you have an extra guage (which I think you mentioned you tried a different one) take the air line off the one on the dash and replace it with the other one ( no need to reinstall the dash) you can use any air guage. It's hard to diagnose when the truck is not in front of a guy. Are there any air leaks anywhere on your tractor? If it drops below 60 psi your buzzer needs to activate-sound off.

Interesting. never thought of that.did your gauge just drop to zero with no buzzer then come back to life? as thats whats happening to mine..

The best way to reset the cab controller unfortunately, is to disconnect ALL batteries form the truck completely, and let it sit for 30 min or so, then re-connect everything. No one fuse will typically do it. i would try that just ensure that is not what happened. It is very common.
