low voltage

I have a wildcat 5th wheel 2004 27RL and have a problem that I have nevr seen before so I'm hoping someone else has. When hooked to a land power I have 110 volts power everywhere needed in the RV. The power in the two outlets in the sleeping area are reading 79 volts. I pulled the plugs and found all is correct. I cannot trace the wiring since it gos up into the ceiling. I checked the fuses they are all good. All other plugs read 110 volts.
Anybody with an idea?
Thanks
Ken

where did you measure the voltage at? in the socket or at the terminals attached to the socket? Also do you have GFI in line?

I checked the socket not the wires. There is no GFI inline.

I think all plug ins are required to be gfci protected in a camper.

My 2005 flagstaff had 8 plug ins with two gfci's to protect 4 and 4.

In other words one gfci protected 4 outlets.
The other gfci protected the othe four.

If I were you I pull it out and check the voltage at the wire. You might just have 2 bad sockets or lose wires. I know on my unit which is not the same I have 7 outlets on 1 15 amp breaker. Also check the GFI as Turbo said. That is a weird problem.

Check voltage to ground. If possible, use an extension cord plugged into shore/house as the ground reference. Then put black meter lead into that ground, and red into camper outlet. If still 97 volts, its a hot wire problem. If you get 110-120 volts, then neutral problem or ground-neutral could be reversed somewhere.

I am trying to remember, but I believe I saw a problem similar when the GFI neutral and line were reversed.

This sounds like a loose wire to me as well. A loose wire will arc causing carbon between the wire and the socket contacts (screw or Press Knife). That carbon will cause high resistance (voltage drop and heat).

Feel the socket when something is plugged in.
A hot outlet is VERY dangerous.

You're right of course, but only when the outlet is under load. The open circuit voltage will be full voltage. I got my money on a neutral problem.

I been waiting to see what the OP found, You got to remember the unit is 10 years old, I'm sure they worked at 1 time. Unless something was added that's a good question.......
