Does anyone know what the on /off switch in a 2005 national dolphin Rv in the rear driver side jockey box is for ?
Located next to phone jack and cable hook up

Water pump?

Try it and then if you have the faucet there with the sprayer see if it works and the pump starts running.

I have the water pump switch next to the dump valve.
This is in the rear jockey box

More than a decade ago we had a 2007 Sea Breeze so I’m working off of memory.

Everything we have talked about... phone, cable, dump valve, water pump switch... in our coach... was all in the wet bay compartment NEAR the rear... but not the very back compartment. But it was ALL in one compartment.

So obviously something different.

Do you have a white light high up on the drivers side of the coach near the wet bay... sometimes referred to as a “utility light?” I’ve seen the buttons on the dash but again... just a thought.

Last in several years on here, and on owning a National RV and now my fourth coach... I have never heard anyone reference a “jockey box” so I really have no idea what this is, or what you are referring to.

Maybe some pictures of it’s compartment and the area near the button, would help me and others assist you in figuring what this mystery button is.

Sorry
I work in the studio business and the boxes on the trucks are referred to as jockey boxes.
I guess in motor homes they are called bay storages?
Anyway, I have read the switch , at on position is for 50 amp service to control A/C heat pump bot units, off is for 30 Amp one unit?

The coleman Mach ac/heatpump is 2 phase system. One phase will run on 30 amp service both phases need 50 amp service. Most coaches that are 30 plus feet that do not have a basement AC unit have 2 ACs on the roof. Generaly it would take 50 amps to run both units. Assuming you are using other appliances in the MH.
