wiring lights

Ceiling lightImage by Generation 3 Electric, Inc via FlickrQuestion:

Hi Bill,
I am looking to wire a room using 3 different switch points. My problem is in the second switch point. In this gang box I will have one 3 way switch used to light the room and a second single pole switch to light an outdoor patio light.
Currently I have a 14-3 line coming in with power from the first switch, a 14-2 coming in from the patio light and finally a 14-3 line coming/going to the final switch in the room.
The 14-3 line are red/white/black/ground and the 14-2 are white/black/ground. I thought I had it figured out, but the way I currently have it the indoor switch only shuts power off to the other switches and the patio switch will turn on the outside light, but only with the other switch "on".
Any help would be GREATLY appreciated! Thanks!

Hi Ryan,

Great job attempting this yourself. Switch is not as easy as most people seem to think until they get stuck. This is not a beginners project so don't feel bad if you need to call in a pro. Let me see if I can give you some advice to help you out.

I can't see you wire so it is not possible to give you a wire diagram or to tell what goes where.Instead I want you to think abut what you are trying to do. You have a pair of three-way switched and a single pole switch. They are two separate controlling systems.

What I want you to do is find your feed in the 2 gang box and put two jumpers off of it. One for the single pole switch. The other for the three-way switches. Solve them separately. It sounde like you are trying to do it all at once when you really need to be breaking it down into smaller sub-systems.

Good luck,
