I have a weird problem regarding grounding:
I have a computer, printer and a LCD screen connected to the electric outlet through a power strip. My computer is zapping me when I touch the body so I tried to touch with a tester the screws on the computer body and saw that the light was on. Then I touched the ground hole in the electric divider and saw that it was on as well.
I thought that it was problem with one of the peripherals so I removed each one of them but as long as one of them was connected the light was on in the ground hole. If I remove all of the appliances then the light in the tester is turned off. (Also, when I touch the ground hole directly in the outlet, it's off.).
Then i thought the outlet was the problem so I connected them to another outlet but still, same thing.
So i thought the power strip was the problem so I changed to three different ones but still the same thing.
The tester light is full on, not weak, and the computer is zapping me good (not very intense but every time I touch it and it's not very pleasant). What do you think is the problem ?
