Last year, I bought a black and yellow voltage detector, from the electrical aisle at Walmart. I was on the job with a friend. He had one, and it was totally useful. Hold it near a power line, push the btton. See if the line was charged. If yes, it beeps and chirps and warbles.
Mine worked for a couple months, and stopped working.
Harbor Freight had similar one for sale, takes AAA cells. Neon bulb, now days probably LED. Flashes in case of power. Today it didn't work. Not sure if the leaky Energizer cells were the problem.
Anyone have a brand and type, that works and is inexpensive? . Christopher A. Young Learn more about Jesus
