Born in a Basement in Ontario.

My dad had a problem. He couldn't tell if a spark plug was actually firing without dragging out a bunch of wires, clips, and grounding setups. So he built something better.

A wireless diagnostic tester. Hold it near the boot, crank the engine. Three lights tell you everything you need to know. No direct electrical connection, ever.

Three Lights. One Answer.

Green — Powered on.
Red — Voltage detected at the plug.
Blue — The plug is actually firing.

If you're not seeing blue, that plug is your problem. It's that simple. No guessing, no special skills, no shop equipment required.
