Air gauges keep fluctuating

I notice that my (2) air guages keep fluctuating as I'm driving and the "Low Air" lights come on and off as they fluctuate. Anyone have any idea as to what could cause this?

What Motor Home, what Chassis, what engine?

These make it easier to help if we knew what we are dealing with

You may have a bad parking brake canistor, that's if you have air brakes. Chock your wheels and then release the parking brake then listen to see if you can hear a air leak. Set parking brake and see if it still leaks. If not Ithink that's what it might be.

My Freightliner chassis had the same problem. After replacing the gauges a few times the wiring harness was replaced and that solved the problem. They have been a problem for freightliner. It was replaced under warranty.

If the gauge goes to zero momentarily and then back to full pressure again, I would say a wiring problem. But if the fluctuation is between, say, 60 psi and 120 psi, you may just have a severe air leak. For example, a cracked hose to an air bag would result in a major pressure drop, which the compressor would then recover as soon as the pressure drops to the trigger point that turns the compressor back on.
