Ok, so sometimes my air gauge will jump in pressure, the compressors sometimes are on and sometimes off when it does it. Usually it does it when the compressors are on. Here is a video. Any idea what causes this?

The only thing I could think is maybe a loose wire? Check all your connections, is the first thing I would do.
Ight, I will do it. Its irritating watching it jump around!
Did you run the wires exactly like the directions?
The ground wire from the gauge has to be connected to the ground AT the sending unit.
I can post a diagram if you don’t know what I mean.
Ya, draw one out just so I can double check.

does it do it when ur not driving as well and truck is still?
From AZ:
It does it when the compressors are on mostly.

Mine jumps up and down while it’s filling but nowhere near that dramatic, maybe up and down 5 psi until the comps stop. Check the wires like they said, or maybe look for leaks.
