As a youngster, I almost cause my mom and dad to sell the house. I would wait until everyone went to bed. I would pull out anything electrical found in the neighborhood. Get a screwdriver and probe until I saw sparks or felt my arm go numb. We, kept a box of fresh fuses. Mom and dad sworn it was bad wiring in the home. God bless them. They left here not knowing it was me. Now, I confess. Now, I probe around 480v.
