While I was cleaning up some wiring in the living room and hallway I noticed that the wire leading to the living room switch wasn't the same wire that actually made it to the switch, which presented a little dilemma. And as you guessed I opened up the wall and found another hidden junction box. To top it off the wire leading to the box was spliced to another one with marretts 4 inches before getting to the box. Now there is one wire from the light to the switch, which is run though the joists and not below them beside the strapping for the drywall, that could cause a problem. As I was already standing on a ladder with a drill in hand, I pre-positioned the wires for two lights we'll be installing above bookcases we'll be building later. Today we also looked at locations for lights, plugs and switches in the kitchen and I'll be running wires to them soon. Just one thing after another, but nothing too big that can't be corrected immediately.
