My dad spent Saturdays pulling apart an old motorcycle convinced it was a fuel problem. Turned out it was a dead spark plug. Stuff like this happens all the time, if you've worked on a small engine you know what I'm talking about. So he built something to stop that from ever happening again. TruSpark Pro is a wireless spark plug tester. Hold it near the plug boot, crank the engine, and it tells you in seconds whether your plug has voltage and whether it's actually firing. No wires. No clips. No grounding. Nothing touching anything. 🟢 Green — Device is on and ready🔴 Red — Voltage is reaching the plug🔵 Blue — The plug is actually firing Red and blue? Your ignition is fine. Look at fuel or air.Red only? The spark plug isn't firing. That's your problem.Nothing? No power reaching the plug — check your ignition system. Three lights. Less than ten seconds. No more tearing things apart to find out. Ships fully charged and ready to use straight out of the box. Because TruSpark is only used in short bursts during diagnosis — not run continuously — one charge is estimated to last at least 1-5 years depending on frequency of use. We charge every unit before it ships. Realistically, most customers will never need to charge it again. We include a free USB charge cable in every order just in case — think of it as a free bonus, not a necessity. (Some disassembly required to recharge the buit-in battery pack.) ✓ 100% wireless, no electrical contact required✓ Works on any engine with a spark plug — motorcycles, ATVs, snowmobiles, lawnmowers, boats, generators✓ Microcontroller-based with custom firmware — built-in intelligence, not just a passive sensor✓ Auto powers off completely after 1 minute of inactivity✓ One button operation✓ Hand-built in Ontario, Canada — not a dropshipped gadget from overseas✓ Founders Batch — 100 units only ⚠️ COMPATIBILITY NOTICE: TruSpark works on traditional spark plug boots and plug wires only. It is NOT compatible with coil-on-plug (COP) systems where the coil sits directly on the spark plug with no visible wire. Most motorcycles, ATVs, snowmobiles, lawn mowers, boats, generators, and older vehicles are compatible. Most modern cars and trucks (2005+) use COP systems and are NOT compatible. Unsure?
