Today I saw something I have not seeen before, When testing some receptacles in a house, I had my plug tester light all 3 lights. Thinking that maybe something was wrong with the tester I went out to my truck and grabed the two other plug testers I have and restested. All three plug testers had all three lights light up. The recep was wired correctly. Voltage test with a meter was normal (116.5 volts). So far I have not found any thing wrong. Any Ideas ?????
