To use, attach the alligator clip to the engine, connect the other end to the spark plug wire and check the spark length through the small window. The longer the spark gap, the stronger the coil. Designed to ensure compatibility with a wide range of automotive ignition systems, it is an ideal tool for automotive maintenance, small engine inspections, ignition coil testing, and lawn mower maintenance.
