Re: Gfi?
What you're claiming is that some specific tester has internal circuitry that detects the GFCI and then performs differently on a GFCI than it does on a regular duplex.* There may be such a tester - the link you posted made no such claims and it didn't contain sufficient details to determine whether the tester illustrated had that capability.* I doubt it does but leave that aside for a minute.* Now we have to assume that the OP has such a tester with that specific capability and that is why his problem is occurring.* Most testers that you pick up at Home Cheapo or Wallyworld can't even test the GFCI function, let alone having*this added ability to detect whether they are plugged into a GFCI outlet that you are*now claiming.*
Like I said - I'm not convinced.
