Power from Fixture to Switch Not working


I recently replaced a fixture in my kitches with a recessed can light. I orginally powered up the light with black to black and white to white(standard). Once I hit the breaker the light automatically comes on, if I swith either on or off it pops.

I then tried re wiring the switch after researching this. I took the 12 wire from the switch and put the white wire from the switch to the black wire of the feed wire. Then the white wire from the feed to the white of the fixture, the black wire from the switch to the black of the fixture. Nothing happens at all. I am stuck, aside from popping the breaker and switching every wire together where do I go from here?

From my understanding, this is what it is like..
I would try to replace the switch, because when the breaker "popped" you created a dead short. This could have burned the switch.
By the way, are you getting power from the feed?

rgsgww: You got that backwards.. the hot feed TO the switch is the remarked white; the switched feed FROM the switch is the black.

madjoseph: Check your bulb. Check to see that you still have power from the feed wires, and connect the switch loop as described above. Replace the switch if things still don't work.

To RG,

The feed to the switch in a switch loop MUST be the white. NEC 200.7(C)(2).

Switch loops.

Another way of putting it is that the (black) hot lead for the light fixture is connected to a non-white wire coming up from the switch and furnishing switch controlled power. The other wire coming from the switch (may be white) connects to the hot feed (unswitched power). Both ends of a white wire connected to a switch are marked (taped or stained) with red or black.

My bad, my bad.
The white wire is supposed to be the feed because, if it was tied to a neutral, on accident, there wouldn't be a dead short-It simply wouldn't work.
The picture has been corrected.
