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..

First, do you have air in tanks on both sides? Check using drain cocks. There aren't any wires to guage other than for the light. 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. Where are you at?
