Electrical outlet wont work

I have a 1995 Nash 20n and me and the wife love it but the electrical outlet by the kitchen sink does not work. All the the other outlets in the tt work but that one.

When measuring voltage with my multi-meter i get 119v on all the outlets that do work and 89 across the one that does not work.

I put a new outlet in and that did not work. Any ideas? We've done our best not to let this older tt go downhill and have tried to keep everything working but this one has me stumped.

Pretty much proof positive one of your outside outlets is bad. About thirty years ago I stopped fooling with switches and receptacles and started using fork terminals. #6 fork X 10-12 gauge wire. Soldered terminal to wire. Why? It was after I proved to myself this superior connection noticeably reduces the temperature of the terminal and wire end. Spray protector atop the finished work and it will remain perfect for decades. Outdoors I squeeze silicone grease into receptacle and extension cord female connectors. Fillemup with grease. The increase in lifespan is nothing short of dramatic.

my bet also is that you did not fix the problem yet.

Did you load up the outlet for the test?

Are you using a digital meter? Your measured 89 volts is probably not really there. Digital meters can and do detect "phantom" voltage caused by capacitive coupling. The posters above telling you to look for a bad connection at another outlet are spot on. Info about phantom voltage:

You need to pull out that outside outlet and inspect the connections. If the problem isn't there, start pulling other outlets till you find the problem. A loose or corroded connection can become a hot connection and a fire hazard. BTW, I hate those self-contained outlets with the push in wires, I replace with real outlets wherever possible.

Thanks for all the replies. I got busy at work and wasn't able to revisit my problem outlet till this week.

After playing with the outlet a bit and stripping the wires and punching them in the press in connections on the back I still couldn't get it to work. I gave up and read some of the replies about outside plugins this morning and went out to see if they worked. I plugged in a trouble light to the two outside plugs and they worked, Next I went in the tt and tried the gfci outlet by the bathroom sink and they worked also.

I then went back to the outlet that wasnt working....and now it works. I dont know if when I plugged into the outside receptical I jiggled something as that is the only outlet I never played with back in the summer when I worked on this problem before or earlier this week when I again tackled this problem?

Bad connection I guess.

I have seen it, a very very very bad connection.

Now I have to run Radio calling.

Bad connection.... First: That outlet gets it's power from a GFCI outlet somewhere, Likely the bathroom.. likewise the patio outlet gets it's power from the same source

Suspect list includes the connections behind the GFCI. the outlet in question and the patio outlet. also all other GFCI protected outlets if any (I have one over the dining room table)

Standard RV outlets are "Quick Box" type, where you lay the wires in a channel and PUNCH them Down.. Now I have had telephone installers explain to me they have been using punch down connections for a long long time and no problems (True, I know I've seen 'em, used them myself) but those connections carry a fraction of an amp. The punch down (And I might add Scotch lock) connectors are great at low current,, but crank up the amps and they quickly fail..

An electric skillet along with a coffee pot and a toaster.. That's a lot of amps.

The connections overheat and burn.. you get hot wire smell (not good, scary in fact) and either a bad connection,,, or a fire.

Next. I've had very bad luck with wire nut connections between stranded and solid wire.. Like in back of the GFCI

So your have one of two chains

Breaker box---GFCI----Kitechen--Other outelts
Or
Breaker box---GFCI---Other outlet(s)---Kitechen---Optional other outlet(s).

(Actually that's 3 differnet chains.

TRhe problem is between GFCI and KITCHEN.


Oh, forgot.. If the kitchen (or the GFCI) is in a slide out, then there will be two junction boxes under the slide out, one on the moving part one on the main body part.. Those too are on the list.


Finally.. though I replaced my failed Quick Box with another just like it, I also added some heavy duty outlets to take the load off it (it's not in the kitchen, a space heater took it out.. I now have dedicated space heater outelts)

If replacing them I really like the idea,, where you can do it, of using a traditinal box and outlet and bending bare wire around a screw and tightening it down.. Far better connection, 100s of times the contact area, less likely to flame on. If the kitchen is the first outlet in the chain try this.. If not.. Well whatever outlet you replace.. If you can do it that way, do so.. Might not be possible.

(NOTE: I really like the way this motor home is layed out.. where they put the pwoer distribution panel is central and easily accessed, both front and rear I put one HD outlet (15/20 amp) in the bedroom 20 amp breaker all to itself, about 18" of 12ga wire hooking it up If you pull the outlet and look in the hole you actually SEE the back of the outlet box.

The other HD outlet went in the living room 15 amp breaker (was out of 20's at the time) 12 ga wire, about six to 10 feet (did not measure) runs across to the wall following existing wire channels and into the wire/plumbing channel that services the front toilet.. Across behind the toilet (under the riser) and to the outlet, Again wide open run, no obstructions to drill through.. That puts heaters where I need it most.

A 3rd single 15/20 (not a duplex) is fed off the rear A/C circuit, which can be fed by a 12 ga cord.. (You do not use heat and A/C at the same time) plus there is a dedicated 12ga extension cord so I can run up to 4 space heaters without overloading... (I have yet to do that but the extension cord and the dedicated 15/20 single were installed at different times) But the way they layed this house out. Adding all those outlets was child's play.
Home was where I park it. but alas the.

Does your unit have an outside outlet?

Once we were stumped after checking all outlets as you have done...until someone reminded us we had an outlet on the exterior, and it turned out to have been tripped.

As others have said or implied, you need to check the wiring at the outlet preceding the one that's not working, assuming it's not the first one in the circuit (which is likely since the others are working). You have a bad or open connection somewhere. Find it and fix it rather than letting it sit and not using the malfunctioning outlet, as this could be a fire hazard.

First suspect is a GFI but that would usually be a second outlet not working.
Probably need to inspect the string back to the breaker. Most probable IMO is the exterior outlet could have a corroded connection.

you have a voltage drop on that one so you prob have some burnt/melted wiring inside the wall somewhere, you'll have to trace it down and clip it out of there and install some new wiring. Look for chewed wire from rodents too
