(First time quiestion here, so correct me if something's wrong)
I recently installed a lamp on the ceiling (a metallic chandelier). Two wires connected to the ceiling (one phase and one "zero"). The grounding is connected to the top metallic part of the chandelier (the cover for the wiring). So everything is pretty much ok - the thing works as expected, all 5 lamps work and give light.
The problem: when I touch that top metallic part (the wiring cover) of the chandelier with a tester it starts flickering (a have this "pencil"-looking model of a tester). So basically some voltage there on that thing, but it is not stable - the led in the tester turns on and off at random. It is also not some temporary thing - I tried holding the tester there for longer times and it does not stop.
So the question is - should it be this way? Did I do something wrong? I mean there is not much to connect there - two wires in the ceiling (no grounding) and two wires in the chandelier. Help, please.
Ok, I just returned from the apartment. And I am getting a bit suspicious - the tester I got lights up even when close to pretty much any wire (the wires I tried were all isolated). The LED inside it does not go full-power though - it is quite dim when testing those wires. So, basically, it is getting some phantoms there. So again - I am starting to think that the tester I have is not going to help to find out anything. And I still do not have a volt meter so it will be a trip to the hardware store for me.
Just in case - I get no readings whatsoever with lights off. And I double-checked the neutral - it does not touch anything. In any case - I think I need a proper tester before proceeding.
UPDATE 2 Problem was solved. I was a bit (or a lot) stupid and got the wrong tester. I tried it out with a simple wire and got a reading (as indicated in the previous update). And then I got a normal tester that did not get any readings on any parts of the chandelier. I also tried it out with the phase wire coming out of the ceiling and it did light up (that way I ensured that the tester works). So again - thanks for your answers, guys. They really helped a lot.
