Electrical engineer here - question on my own home for a change. Newer home, with a 3-way switch-controlled receptacle in one room. Over Christmas my wife unplugged the lamp that was being used on the recept, and plugged in some LED lights. We noticed that when the switch was off, they still lit (dimly). Finally got around to metering the receptacle today: 123 volts when the switch is on (OK). However, still 51.4 volts when the switch is off. Standard outlet tester indicates (red light off / 2 yellow lights on) that the outlet is ok from that standpoint. Thoughts on what to do / where to start 'troubleshooting'? I'm hoping this isn't a wiring issue. I'm a handyman also, but typically prefer projects by choice! Thanks in advance.
If the romex was stapled too hard or pinched the voltage could be coming fromhot feeding the switch if it's in the same cable. If it's a switch loop that's most likely the cause
