added new switches, one of 2 old switches doesn't work anymore
I had 2 switches in an electrical box, one did a light on the porch, one did the light outside. It had a 14/3 BX and a 14/2 BX.
I added a fan to the porch, so I needed 2 more switches in the box (one fan, one for the light on the fan)
I pulled the wire (14/3 and 14/2) to the box for the fan which went on a new breaker, those switches work great
on the old one, the neutrals in the box were tied, I left that. From the existing switches each switch had 2 screw downs (a and b we'll call them) B from switch one was tied to A from switch 2 (both were tied to a black which had a loop around B from switch 1 and finished on A from switch 2) This was the black wire from the 14/2 which I presume went back to the breaker from all I can tell.
the other 2 wires were tied back to other 2 wires from the 3 wire (the neutral already being tied off)
on the new switch (a leviton 2 switch in one slot switch I bought) I tied the black wire to one side (looped around one of the screws and ended on the other) and tied the 2 wires from the old 14/3 that weren't the neutrals to the other side and thought it'd be good.
Turns out only one of the lights works now. Did I do something wrong? I checked the power with one of those current detectors and when I flip the switch there is no power, but I don't see why.
It's too dark to start pulling it back out since flipping the breaker turns the lights off in that room, so any help is much appreciated.
