Hi all,

I just found a weird problem with my outlet in the main washroom, there is no power when I plug in the power shaver or whatever things that I plug in. But the light, fan on the same circuit are still working.
I turned the breaker in the basement few times to make sure that there is nothing wrong with the breaker.
I though there is a problem with the outlet, I bough new one to replace it. Same problem, no power at the outlet, but the lights and fan are ok. I test the wire at the outlet, it does has power. The light on the test pen flashes and beeps like crazy. I have a picture to show

Has anyone experience with this? Please advise.
Thanks

I suspect the outline is wired to a ground fault interrupter outline somewhere up ahead on the line and that outlet is tripped. Many of the GFI outlets allow you to control more than one outlet.

Thanks for replying HamS.
Is there any instruction how to trace it out and fix it?
Or do I have to find an electrician?
Thanks

The problem is most likely that the neutral (white wire) is not connected. The other possibility is that you have a bad connection, this will show wvoltage but will not pass any substantial current.
Follow the circuit back to the box that is feeding this one and see if all connections are correct. The only way to find the problem is to find where the white wire is not properly connected. It could be in the switch, t he light or another receptacle. The only way to find t he bad connection will most likely be trial and error as it can be a lose wire, one that has slipped out of a wirenut that was not properly tightened down, or a wire that is plugged into the back of a receptacle ( called back stabbed and can cause lots of problems over time) and is lose.
As you are showing voltage at the receptacle the possibility of a GFCI being tripped is not likely as that would stop the voltage.

Thank you brimus.
Hmmm, it sounds like a bit complicate for me, but I will try to hack on it. I am sort of electrical illiterated so it going to be a challenge.

I agree with brimus. You show power on the black wire. They always show power even if there is an open on the common side. Your white wire is not connected someplace. This is going to be like an Easter egg hunt. go in the attic if you can and follow the wire to the nearest junction box. Make sure the power is off and check those white wires. from there go on closer to the circuit breaker panel and check the next junction box on that wire. Check the white wires. Of course since you are in the box you should also check the black wires. It is possible that the black is almost disconnected. That could give you enough power to indicate a hot wire with your tester but not enough to light a bulb or run a tool. Work you way back to the circuit breaker panel. you need to turn off the main breaker to do this. Never know what someone has done to your electrical system. There are codes but…....

Might look in the circuit breaker panel before you go to the attic and mess in the insulation. The common could be loose or it might have arced in the panel. just a thought
