....Here is where I think things might be getting weird... The switch that used to be there was a three-way. I have tied the two wires that I need to make it a two-way switch. Perhaps I have done this wrong, and somehow the signal used to work, but now something is causing enough interference to make it not work....
What happened to the other 3-way switch? Did you take it out or just leave it in place? Try switching it. If you have shorted the right pair of wires it shouldn't make a difference. If it does make a difference, then you may have the wrong two wires or a defective switch.
A conventional 3-way light is wired like this. The hot line goes to one switch and two wires connect the two switches.

For the sake of this discussion, I've labeled the original standard switches A and B. While I prefer to replace 3-way switches with 3-way X10 switches, shorting the right pair of wires will allow you to install a standard 2-way X10 switch. For the sake of this discussion, switch B is being bypassed and A is being replaced with a standard X10 switch.
Let's look at why it might not work, however.
- Red dots are shorted. If the "bypassed switch" B has a failure and does not make connection in one position. Rare but possible.
- A red dot and the blue dot are shorted. This leaves you with only a 33% of guessing the right pair for the X10 switch. - Also let's say you shorted the bottom line to the blue dot and left switch B in the up position. Then you installed the X10 switch where switch A was using the top line. Guess what? It would work but only as long as switch B stayed in the up position. Murphy's laws say that at sometime switch B will be switched down causing the circuit to fail.
Best bet, if you're guessing wires, is to short all 3 wires, both reds and the blue. This will give you a 67% chance of guessing the right pair for the X10 switch. $2 at WalMart will buy you a neon tester and increase your odds.
Remember: Unlike a conventional switch connection, X10 must have a flow of current through the switch at all times. This is why X10 switches are made just for 3-way applications. Also remember to put a wire nut over any extra wires!
