I don’t need to know how to report this, I’ve already done that. For my own information, I’m just curious as to what is going on. I also know that the three-light tester is the least reliable tester, but I’m using it to illustrate this oddity.
The GFCI would open when it’s internal test-button was used, but not with any of my testers.
(Pic #1) Plug in the SureTest and get an “open-ground” indication.
(Pic #2) Plug in the three-light tester and get an “open-ground” indication.
(Pic #3) With the three-light tester plugged in, I plugged in my SureTest which now gives me a “reverse-polarity” indication - at the same time, the three-light tester now indicates “normal wiring.”
(Pic #4) While testing the GFCI through the SureTest, the three-light tester goes back to the “open-ground” indication.
It didn’t matter which tester was on top, the results were always the same.
So what’s going on? Is this just simply an “open-ground?”
