Trent Tarter 5 Report post Posted August 24, 2017 I found this device connected to an exterior switch. It's been abandoned as the wire is cut below it. Just wondering what could be? Quote Share this post Link to post Share on other sites
Bill Kibbel 68 Report post Posted August 25, 2017 Never seen it. Guess 1. A lightning arrester. The second wire slowly discharges to a ground spike. Guess 2. A transformer for an in-ground mole or gopher zapper. Quote Share this post Link to post Share on other sites
