A must-have item for testing for spark on internal combustion (gasoline) engines. See if you are getting spark to the sparkplug in any internal combustion engine. 1. With engine off, remove sparkplug wire. 2. Attach black connector to sparkplug. 3. Insert metal end of tester into the sparkplug wire. 4. Try to start engine. 5. If ignition circuit is complete, the bulb will flash.
