The outlet at the RV’s dinette is dead, as is the one in the overhead cabinet directly above it. All others work. The circuit breakers at the control center at the foot of the bed are hot. Somewhere between the two is mostly hidden and inaccessible. What do you think? Thanks. —Jack, 2017 Winnebago Via 25P
I love the Winnebago questions as I can go to the website and get 3D drawings as well as wiring and plumbing diagrams for every model in the owner resources tab. Here is what I found for the 120-volt wiring of your Via.
The RV outlets are powered by the distribution center and the dedicated circuit breaker. A 14-2 brown wire first goes to a 110v connection below the floor and then to the 1000w inverter located in the compartment directly in front of the entrance door.
From the inverter, it is wired to another 110v connector below the floor and then the receptacle in the bedroom for the satellite prep and one for the bedroom TV receptacle. Then it is run to another 110v connection box located under the wardrobe, and ganged from there to the TV receptacle, Sat Prep, and then the lounge receptacle. This makes sense as the TV is located on the back wall of the slideout dinette booth.
Connector in wardrobe extends and retracts
With the 110v connector located in the wardrobe which is part of the slide, it would extend and retract, which could have created some resistance and pulled apart creating an open situation where nothing downstream would have power. These are not GFCI circuits as those come off the distribution panel on a separate circuit breaker and go to the bathroom, exterior, and galley receptacles.
With the line going to the inverter first, it would have a transfer switch that automatically connects 120-volt power from the distribution center when connected to shoreline power or a generator to the outlets. It is basically a pass-through feature rather than pulling 12-volt power from the batteries and providing 120 volts through the inverter to the outlets.
Where to start testing
I would start at the inverter and verify there is 120-volt power to the inverter, then follow it to the bedroom TV receptacle. You can use a simple non-contact voltage tester at the receptacle or even just touch the wire along the way.
If there is no power there, then you need to look at the inverter or the circuit breaker in the distribution center. If there is power, follow the line farther down and verify power to the connector under the bed, then to the connector under the wardrobe. Notice there is a “flex” cord, as this is the wire that needs to move with the extension and retraction of the room. If you have power to the connector under the wardrobe but not to the remaining outlets, it is most likely a bad outlet just after that. These can go bad and not provide power to and from, so it would need to be replaced.

Two of our RV’s outlets are not working. How can we fix them?
We had an electrical problem with our Alpine 3250RL 5th wheel. My husband, John, found most of the problem and fixed it, except for the outside receptacle and the kitchen island receptacle. Those two outlets still don’t work. —Linda
