I have an outlet that stopped working. At the same time my front porch light also stopped working so I assumed they were connected to the same wires. We tested both the light switch & the outlet & got good voltage readings on both - so power is coming through. But nothing works when plugged in & porch light still won't work & it's not a burnt out bulb. Any ideas of what is going on? This is an older home, built in the 50's, so electrical wiring is original to the house.
