Air pressure dash gauge

Does anyone have an easy way to figure out why my dash airpressure guage does not show any pressure on my 89-345LE with a 454? I assume the sensor is on the tank, but don,t know. What is the simplist test to determine where the failure would be? I do have pressure in the bags and still have air horns and system seems to be operating OK!
Thanks in advance

There is going to have to be some kind of pressure transducer and it is most likely mounted back near the tank or in the compartment where the compressor is. I'd start there and see if you can trace the wiring from that point.

I'm guessing here but I would imagine that it will have one wire that heads up towards the front of the motorhome.

Unfortunately thats about all the clues I can give you.

Good luck!
