Home was built in 1987. Garage had a few GFCI protected outlets. There was one separate outlet that was only 2 prong (located about 3 feet away from a GFCI outlet). It showed a weak signal with my light tester. When I put a volt meter on it, it showed 1Volt.
- What is a 2 prong outlet doing in this house/garage?
- What would a 1 volt circuit be useful for?
The only thing I can think of is the homeowner replaced a faulty GFCI with a an old 2 prong outlet they had laying around. There was subsequently a fault. And now it only shows 1 volt after the fault.
