where to begin?

to begin: at the moment my question revolves around my electric oven. when i connect it, all hell breaks loose, that is my sink gets electrified, the metal gas line behind it gives shocks.

i pulled out the plug from the oven to the wall outlet, the oven by the way functions perfectly. the oven itself has 3 wires. brown, blue and yellow (ground). I turn on my multimeter to continuity check, which always reads "1" at start. i checked for continuity with my multimeter and i get a readout of 1900 or something like that between the brown and blue. I mean, shouldn't this be absolutely "1", no connection at all?

and, in all the house circuitry, when i do a continuity check between the positive and negative (is this correct terminology?) holes in the outlets, i get continuity. that is, a connection. As well as continuity between the ground and any other wire. my fuses do not blow or anything. Is any of this normal?

thanks

Sounds like a serious problem and if you are not a sparks then it's time to get one in. possible causes could be your main earthing is disconnected or not correctly connected hence why the fuses are not blowing, no main cross bonding , cross polarity on the cooker outlet. Double check the oven is correctly connected, Prove the red wire which should be live is live. If you are not sure then don't go trying.

Hope this helps

I agree, sorry mate, but it sounds like an earth problem, hence the shocks from your gas and water. It is not anything you should be looking at yourself, you need to get someone in
