Outlet circuit problems

[Abnmarine]

I’m having a problem with one of my 110 volt circuits on my 22B class C. This has happened both at a campground and while at home. I’ve done the following to to try to find the issue:

1) Camper is 30 Amp

2) I have three GFCI outlets on one circuit. These work correctly.

3) I have 6 non GFCI outlets on one circuit that do not work.

4) Using a multimeter I have 124 volts coming off of the breaker of the non GFCI outlets. I did this by using the hot lead on the black hot wire and ground on the white neutral wire.

5) All wire connections are good at the breaker panel.

6) I removed all 6 outlets to inspect their wiring. They all looks good. Nothing burnt and solid connections.

7) When testing the bad outlets with the multimeter I see the following for each:
Hot to Neutral is 95 volts
Hot to ground is 124 volts
Neutral to ground 24 volts (should be zero)

8) When testing the good outlets I see the following:
Hot to Neutral is 124 volts
Hot to ground is 124 volts
Neutral to ground is zero volts

9) I’ve inspected what wiring visible and don’t see anything wrong.

10) I ensured to have nothing plugged into the outlets when testing them.

11) I do not have an inverter.

12) There is only one power feed from the transfer switch to the breaker panel.

13) Problem exists when on either shore or generator power

14) I don’t have any outlets in any storage bays and none of the six are GFCI. The six outlets are for the following locations:
Bedroom TV, Bedroom wall, Nightstand, Refrigerator, Booth table and front TV cabinet

Greetings and Welcome

Have you found any junction boxes?
We have 1 screwed to the floor in the bedroom under the drawers.
Another 2 under a false floor under the sink.

Let us know.

Thank you.

So far I have not found any. My breaker panel is under my bed and the wiring runs along the floor and wall with a carpeted cover over it. I will try to look some more.

If you can figure out what order they are wired in, then you could disconnect each section, starting from the farthest away, and check voltages. You might find the culprit link. Probably a smashed wire somewhere.

Sounds like a poor connection on the neutral line for that circuit.

Plug in a simple device like a fan into the last circuit on the string and turn it on (a light would work as well).

Measure ground to neutral with the load - it will probably be line voltage (120 VDC). This indicates the neutral line is not connected properly to the neutral buss in the power center. Now you just have to find out why.

That's where ours is, the junction box in the bedroom is in the slide.

FYI: label the draws when you take them out, I didn't when insulating the outside wall, still trying to get the draws in the right order

Missing neutral is correct. Since all 6 outlets are affected, it is somewhere between, or at, the panel and the first outlet in the line. Look for either a j-box or a poor connection at the outlet. But it is a neutral problem.
