Instrument Panel Problems

Recommended Posts

I have a 2008 Fleetwood Discovery, cummins engine., freightliner chasis. Had the fuel pump replaced and the house batteries. When I went to pick it up it started fine but after a minute or 2 the instrument panel was going crazy, including even hearing the A/C fan speed change. Instrument panel would look normal then air pressure alarm goes off, both primary and secondary gauges go to zero, come back an forth and voltage goes low, low voltage alert comes up. All goes back to normal and then it happens again and again. I have always had a low air pressure alarm (without the gauge changing) that freightliner could never solve even after changing out the light bar.

Mechanics scratching their heads.  Any ideas?

First place to start, check the grounds and for loose connections. The dash area is more susceptible to vibrations due to all the wires moving ever so slightly.
