Question:

Wiring the switch to my 2 speed attic fan.?

so there are 3 different wires coming into the switch. 1 black wire and 2 white wires going to the attic fan (i assume one for high and one for low). the power seems to be coming from the black wire which has inside of it, one white wire (neutral) one black wire (hot) and one bare wire (ground).. the same for the 2 white wires. the switch goes up (^) for high and down (v) for low and has 3 places to attach the wires to. the top, the bottom and the middle.. can someone tell me how to wire this damn thing?

Answer:

Attic Fan Switch 2 Speed
I think you are describing NM cables(Romex). What you have is: 1 black romex with a hot(black) a neutral(white) and a bare ground. and 2 white romexs with a black, white, bare each. right so far? What you probably have is the hot and neutral going to the switch j-box (black romex) and the 2 white romexs go from the switch to the fan j-box. I think I need more info. Do you have a test meter? Are you sure the black romex is the Hot and Neutral? When the wires are disconnected are there other things that don't have power to them? Did you undo the neutral splice? If you could send this info I think I can walk you thru it.
Wire nut all the white neutral wires together. Wire all the bare ground conductors together. The the hot wire will attach to the terminal labeled common and one each of the other 2 black wires will attach to the high and low terminals. If it runs high while low is selected etc, the swap the last 2 and try again. PS any time there are multiple conductors in an overall covering it is called a cable. You have for example 1 black cable and 2 white cables.
