Installing a ceiling fan, now other outlets and bathroom fan don't work
So I was fiddling today, and installed a jb for a ceiling fan in my bedroom (where there was nothing before). My initial plan was to take the switch next to my doorway which switches one outlet and turn that into a dual switch for the fan/light that I was going to install, and replace the outlet with one that would always be on.
After installing the jb I cut the 12-3 wire in the attic going from the light switch to the switched outlet and ran it to the jb for the fan. I then installed another jb and put the sliced end of the 12-3 (going to the switched outlet) into it. I capped off the red wire and connected the white/black to new 12-2 wiring. I ran that wiring into an existing box on a different circuit that is powering bathroom lighting and a fan and one other thing (not sure what off the top of my head).
I went back downstairs and replaced the outlet with a new one and capped off the red wire.
Turning the power back on (hunny came home and wanted the lights back on, so no time to install the fan, or swap out the light switch for the dual switch) everything worked as expected except the bathroom fan and the replaced outlet. Note, the bathroom light, which is in the same set up as the fan, and comes from the same box, was working without issue. The outlet was reading 120ac v on my meter, but then when I tried using the shop vac in it it hummed like it didn't have enough power. I put my meter back in and it went from 120 to 0 when the vacuum was turned on again.
These are 15a circuits.
Thoughts?
I won't be able to play with anything tomorrow or tomorrow night, but I'll be back trying to figure it out Sunday or Sunday night.
Thanks!

Without knowing how the original switch was wired this will be more difficult. Working backwards tell us what colors and connections were at the switch box and receptacle.

The original switch was wired with black on top and red on the bottom (single pole) and the white connected in the box. (there is a 2nd light switch in that box going to a light on the other side of the room, but this wasn't touched). The 12-3 then went up the wall into the attic (where I cut it) and then down the wall and to the receptacle. Before I switched it out there was 5 wires on the receptacle, 2 whites on one side, a red and a black on the other side (I don't remember which was on top and which was on the bottom) but the small brass connector was taken out of the middle on the red/back side. And a ground connected on both ends.

Tell us where the unswitched power from the breaker comes in and how the existing bedroom switch is wired.
Are you saying that you installed a new fan-rated box in your bedroom ceiling?
You could have an open neutral. Also, check in the bathroom switch box to confirm that the fan and light get their power and neutral from the same cable and that that cable has 120V hot-to neutral.

Pulpo, I considered this, but I'm not sure... This is what I know to be on the circuit:
Bathroom fan (won't turn on at all), bathroom light (turns on no problem), two kitchen lights (both off when testing bathroom) one wall outlet in the kitchen with an alarm clock (on) and a toaster (off) light (on) and outlet (nothing pulling current from there) in utility room...
Seems like there is a lot of "stuff" on it, but with 2 of us living here I'm not sure that I am worried about it being overloaded (nor do I think this would have caused it to be, but I have certainly been wrong before).

You cannot use parts of different circuits.
Just splice the wires color to color and extend to the new box. Red is probably the switched hot while black is constant hot.

pcboss,
I don't believe I am using parts of different circuits, however I did switch which circuit the outlet is now being fed from (from circuit 7 to circuit 9).
Nashkat, I'll be back in touch with the answers to your questions on Sunday. I'm off to bed now. It was a new fan rated box that I installed. In theory the fan box and bedroom light switch should have nothing to do with the issues as the fan/switch/light are on circuit 7 and the outlet was switched from 7 to 9.

Are the black and red wires connected to the switch in the same cable or two different cables? If two different cables, is one of them a 2-conductor cable and do the wires in it have 120V hot-to-neutral when all of the wires in the switch box are disconnected?
I'm off to bed now.

Is it not standard that, for SPST/DPST switches, the switch be oriented so that the switch is closed when the toggle is flipped up? Especially since most have ON and OFF indicated on the toggle?
Do you have the answers yet to the questions that have been asked?

So these issues are all resolved now. It was a mix of a lose connection in the box, being slightly confused from not listening to Ray (completely) on my last wiring problem (bathroom fan, labeling a white wire to reflect that it was not the standard white).
In addition to the fun things I learned while doing this, I also came across a question of whether I could have 2 wires going to the bottom of a standard single pole switch (seemed like something that shouldn't happen) and found the answer http://www.doityourself.com/forum/el...ree-wires.html
Anyway, outlets, bathroom fan/light, ceiling fan/light are all working as expected.
As always, thank you guys for the help and education.
