Help! Rewiring 3 way switch, cannot get it to work again.

[lethalmonk6]

Long story short, I tried to replace my existing 3 way switch with a new 3 way switch, but I had to pretty much take everything out and my attempt at putting everything back as it was failed because now the ceiling lights controlled by the new switch don't work. The other 3 way switch is located on the other side of the room.

The box itself is a mess and after diagramming it out I am quite confused as to why there are so many conduits coming in and out of this box. See my diagram below.

There is also a 1-pole switch in the same box that does work as currently shown wired.

The lines I've drawn are color coded to what the wire colors are that I see in the box. The blue triangles are wire nut splices.



One thing I have noticed is that when using a non contact voltage tester, there only seems to be voltage coming in from the black wire on C2.
With the 3 way switch disconnected, there is no voltage in any of the C1 wiring.

There seems to be way too many wires that are unaccounted for.
I have no clue what exactly C5 or C4 are going to, and i am assuming C6 goes to the light that the 1-pole switch is controlling. Not sure what C1 is doing either.

Everything besides the lights on this same breaker still works.

Please help me out! I would like my living room lights working again

Lethalfunk all I can tell is you have 3 wires going to the switch and the hot goes on the black wire and the two reds are called travelers go to the other switch but since you have 4 cables. Tie all the whites together and the blacks together because they serve other purposes. Remember always take a picture before you take all the wires apart. Do not attempt this with the power on or better yet call an electrician and I bet it wouldn’t take him 20 minutes to figure this out for you
