exhaust fan in my bathroom. well needless to say it wasnt a hot idea
ill try my best to draw it out.

that is the wall switchbox, and hte ceiling has 2 pairs of white and
black
i cant make sense of this wall box and plus i capped off some wires
what i thought needed to be and now i dont have electricity in my
bathroom at all.....8) good times if anyone can shed some light on it
you will be forever rewarded
Thanks

There is a lot of info missing here, like how many lights, fans,
outlets, there are in the room With everything disconnected, and no
bare wires touching anything, turn on the breaker (most likely there is
only one and you know which one it is?). Use a tester or meter to
determine which cable is live. Now you know the feed into the box.
Shut off the breaker, verify the cable is now dead, then try hooking
this feed to each of the other cables, black to black, wht to wht.
Turn the breaker back on and see which lights/outlets work. Due that
with each of the cables and you should be able to figure out what runs
where and how to then hook it up.
