Today while I was using power tools on the deck, my saw decided to stop working. Turns out that the outlet it was plugged into suddenly lost power along with 2 others in the house. I checked the breaker, and it was fine. I did decided to replace it however (its a 15a). Strangely enough, not all the outlets that are on the circuit stopped working. There is an outlet that my computer and TV reciever are plugged into, and they work fine. They are reading 117 volts, while 2 of the dead ones are reading 17 volts, and the one outside which is a safety outlet, is reading a measly 4 volts. I replaced all 3 outlets with no luck. I am at a loss. What could be wrong?
