Description

The Battery Doctor 21049 is a circuit and spark plug tester designed for 12 to 24-volt systems. It quickly identifies wiring problems such as bad connections, faulty wires, or broken sockets.
A light on the tester indicates a sound battery condition, while no light signifies a short circuit or a low battery. This tool includes an alligator ground clip and a 3-inch metal probe with a cover.
