Hot/neutral reverse indicated on outlet tester, everything works fine.
According to my outlet tester, I have the hot/neutral reversed, but as far as I can tell I don't. The non contact voltage detector seems to indicated I have the hot line in the right position and the other wire is not hot (they are not color coded). This is a GFCI outlet (brand new) that I just wired. There are 4 wires in the outlet. I pigtailed the two "black" (again they are uncolored) wires with a 3rd wire and connected it to the brass screw terminal and did the same with the "white" wires to the silver screw. The power works at the outlet and downstream. Does this mean the problem is upstream or is it potentially a false reading?
Try the tester on another known good outlet to rule it out as a bad reading.
Test other outlets on the same circuit in question with a volt meter.
If the neutral and ground do not show voltage, you should be ok.
Lets see what others have to say :-)
On a side note. Be sure to connect your hot and neutrals on the gfi terminals. Failure to do so will result in a non-gfi protected outlet.
