dash problem

[jdtraveler]

I have a 2002 fleetwood expedition DP w/300 cummons currently winterized. Today I went out to start the coach to keep the batteries charge from sitting for a month and when it started the dash guages were not registering and the idiot lights were all on. Battery switches are in the on position and coach was working fine execpt for the dash. Anyone have a clue

Have you tried turning on and off switch a few times, sometimes after sitting contacts get dirty.

Might want to call Freightliner, I have em on speed dial. They are really nice.

On mine, there's a primitive computer in the dash, called the "LBCU" or "FUBAR" or something, and the gauges are connected in serial out of that thing. If the first one in line goes wonky, none of them work.

If you have that, Freightliner will send you a rig to hook em up in parallel. What they won't tell you is, sometimes if you hook em up in a different order (hopefully, with the bad gauge last in line) sometimes it'll start working again

I don't know about your lights but I would keep the coach on some type of smart charger to keep batteries charged up. Just going out and starting the engine for a bit will not charge them up properly and does not do any good for the engine either. Can you not just plug in your coach while in storage?

Check for loose ground connection under there - that can cause all sorts of issues.

Assuming Freightliner chassis, and gauge package ?
