Get bare!

No, not in that kind of way....well, maybe if you want.

I'm talking about wires, okay? Problem? No? Good.

Make sure you leave your wires bare when you put them on the screw...no insulation on the screws at all. Why? Continuity.

When you do that, you're getting the best continuity you can get...using the entire screw, rather than just part of it. Works much better then.

Oh, and make sure your 3 way isn't bad if it doesn't work. You may just have a wire on wrong. It happens.

Our circuit today was dual 3 ways and a 4 way on a light, with a half hot outlet on a single switch. Three single gangs, one double and a round box. Not too difficult. A little cramped in the box, though.

While on the subject of 3 ways, a good idea is to mark your tracers. Head to your local electrical store and pick up some stick-on wire markers. I use "T" on tracers, "H" on hot....all the way through that line. Makes things easier.

Plus, any other electrician can figure it out if they have to change a switch. And no more having to twist wires a special way. The stickers only cost a couple bucks, I believe. Mine came in a little booklet of them. Every letter, numbers 0 through 9, and a positive (+) and negative (-) sign.

I'd recommend them.
