Us RV techs cal those boxes ECMs. (electronic control module)

Your dash is pretty much all analog. Which specific component or system are you interested in?

ECM is a computer for the engine, this is a computer for for the dash and it's called a V.D.C which I found the location of.

My dash is pretty much mechanical gauges, batt, temp, fuel, air pressure x 2, speedo and tach. They are not working at all.

Thanks

If you have a Freightliner chassis and have a VDC, your gauges are electrical and operate off a multiplex circuit, not mechanical.

Here is a quote from the service manual for the location of the VDC for Holiday Ramblers:

"Right rear compartment, behind the battery box , or on
the roof of the battery box area under the black cover,
or in the right rear compartment.

1st compartment behind right rear axle/tire."

Do a search on this forum for the repair procedure on cold solder joints to repair rather than replace the VDC. Hope this helps.

How do you repair the cold solder joints of a VDC ? allegro5

Had the same basic instructions for finding the VDC but mine is mounted on the passenger side of the cummins engine.

If you never repaired cold solder joints then ask a tech to help you. First find the cold joint by inspection. Usually they are "dull" type joints and also the connections may be loose. In bad cases you may have to use a suction tool to pull off the solder and then clean it Apply new solder. In some cases you can repair the joint by applying heat and re-melting the solder. Use some form of heat sink to keep the heat from the components.

Be sure something is wrong with the computer before attempting this. I use my VMSPc to monitor the computer.

If you are not really proficent is soldering electronics then suggest getting someone that is to help you or take it to an electronics repair shop/ ECM's/VDC's are quite expensive to purchase

the ingition power for the gauges comes from the electrical box located in the compartment below the drivers seat.
The signals come from mechanical senders located on the engine.
The alternator supplies a voltage signal and an ALT FAIL signal via terminals and a relay usually located on the back of the alternator.
Hope this helps.
You might call Monaco support and ask for Jason Guirke. He is an expert on wiring.
