Quick air pressure drops while driving
While driving my coach back from Q yesterday I started getting intermittent "dings" from the dash and the "Level System" light would turn on. About 2-3 seconds after that, the front air pressure gauge would dip to exactly 80 for a couple seconds...

That is when your air compressor governor is kicking in. The leak can be anything.

Can you expand on how that functions please? Is the governor seeing low pressure and thereby telling the...

The governor on the compressor usually is set for 90 psi cut in and 120 psi cut out pressure. If it is getting below 90 it starts building pressure. Not sure why it stops building pressure at 95 on yours. Maybe something else is going on that...

Elliott I recently replaced both my air pressure transmitters do to erratic indications. One was the primary concern and figured they were both the same age and cycles so proactively changing both was okay for me. Summit racing had the best price...

What is your rear air pressure doing? 

My engine air compressor is on at 90 psi, Air pressure never gets below that while engine is on.  And it goes up to about 115 to 120.  The level system dash light is a catch all for any air system/level...

What is your rear air pressure doing? 
I did see the rear gauge behave the same way once and then after that, it was all the front gauge. I got out and sprayed all my bags today...

EDIT #2: Also, on a possibly related note, my step cover slides shut on it's own after about 24 hours. The airlines to it must be pressurized some because even though I can push the cover shut...

So I drove it yesterday for about the same distance and it only came on twice. One time it was definitely tied to a big bump in the road. We came over a bridge with a sizable drop as we were coming off and as soon as that happened the warning...

Mike, if the shuttle valve you are referring to has to do with opening and closing the step closure and the entrance step, it could also be the air cylinders that open and close both of them.... That's simple to check and also a similar problem I...

So today was again different. No drops in pressure visible in the gauges but the dash would randomly ding at me. Again, often when I hit a big bump or slowed down quickly. Unlike the previous times however, it would keep dinging at me instead of...

A room in our pin lock sensor can cause the dinger.

Water in fuel.

Engine ecm faults.

TV antennae up.

TV antennae up.
This has only started happening with this much frequency since I picked the rig up after getting solar installed. Guess what the installer did? He removed the TV antenna and...

Is there a way to properly disconnect that switch/little white box completely so I can rule it out as something sending false positives?
If that switch has two wires then it works in one of two...

Well, it's not the TV antenna, that has it's own light on the dash but I disconnected the switch regardless.

I blocked the coach and crawled around underneath and sprayed everything I could with bubble solution starting from the two tanks and...

Well I found one leak. The piston for the entry steps cover is leaking. I shut it off at the valve behind the steps so we'll see what that does. At the very least I'm hoping it's the reason our air compressor keeps kicking on every few hours.
