You probably have a short pull the kick plate and check your wiring. My buzzer did the same thing on my tractor. Had a stripped ground wire. Cut the wire put a butt connector on problem solved. May be the air pressure switch.

Thanks it was sending units replaced both

Good call on replacing both.
On my '03 379 those jokers aren't the easiest thing to get to. When I traded my '99 379 the sender stuck the day I was trading. 350 miles of that beeper was a little hard to bear.
