I have a double electrical outlet in my master bath that does not work. I replaced the outlet with another of the same type. The wiring is 2 black and 2 white with 1 ground to the outlet. While positioning the ground wire to push the outlet back into the wall I accidently touched the ground wire and the screw to one of the white wires and the test light I had plugged in came on. However, when I plug in the light to the outlet under normal use and switch it on, it doesn't work. Any help would be appreciated.
