Dash gauges malfunction
I have a 2002 Newmar Dutch Star. Last week while traveling the dash gauges began "going crazy" and then quit working altogether. At first the speedometer and tachometer were still working, but now...

Suggestion: add a signature line giving us some specifics about your coach. This can eliminate a lot of confusion.
According to the newmar brochure for your motorhome, you could have a ford, workhorse, spartan, or freightliner chassis. All of these will have different systems for the dash instruments.
If you have a ford, workhorse, or spartan chassis, the below info will not help you.
If you have a freightliner chassis, the link below is the troubleshooting guide for your instruments.
Freightliner guages troubleshooting
The freightliner system has a vehicle data computer that sends data to the message center in the dash (the rectangular light bar). From the message center, a spider harness sends all data to all gauges, and each gauge selects what it needs to function. Your symptoms sound like corrosion or bad connectors in the wiring. Try reseating the connector from the message center to the spider harness and also check the connectors on the Vehicle Data Computer (it will have two air lines going into it). The Freightliner Help Desk may be able to help. It's a free service ( 1 800 FTL-HELP). Have the last 6 digits of your vin number handy when you call.
There is a history of the Vehicle Data Computer having cold solder joints, but this usually affects only the air pressure guages.

Fred, Great Freightliner resource.
I had a dashboard gauge problem last month - false low pressure alert. Cleared it by resetting the cable harness, which involved dashboard disassembly.
Which then involved some dashboard maintenance as several of the screw holes were stripped. Which leads me to believe that it has been taken apart in the past, for maybe the same problem?
Which is now leading down the design concept path of installing an access panel for gauge access without disassembly.
Where does one find the Freightliner Service Bulletins? Is there a website? (I will be googling later on as well)
Cheers,
