    I have a 1993 fld 120. I have adequate air pressure. The buzzer is stuck on but the light goes off. Is this a separate sensor? Tried different bendix circuit board stayed the same? Any hints

    Those high shrieking plastic buzzers frieghliners use are known to short out and either stay on as long as the key is on, or be off at 0 to around 60 psi and then come on and stay on from around 60-125. Lol.
