I purchased an old house, and at the time the outside light was not working when I switched it on. Since then, after trying without success and leaving the switch on, I have discovered the light has come on later. Replaced the indoor switch, did the same thing, thought it was the old light, replaced with a new light, still does not work, tested the wires to the switch and there is no power in them, yet no breakers trip to indicate a short(brand new breaker box recently as well), all other oulets and switches in the room work. Any ideas anybody? I have already spent a fortune on updating and fixing electrical problems in this house!!
