Instant Spark Diagnosis for Gasoline Engines
Stop guessing and start fixing. This visual spark tester allows you to check ignition performance in seconds without removing your engine's spark plugs. Perfect for DIY mechanics and professionals alike.
Clear Visibility with Color-Coded Results
The built-in transparent window lets you monitor the ignition spark in real time. It’s not just about seeing a spark; it’s about interpreting its health:
- Blue-Purple Spark: Indicates a healthy, strong ignition system.
- Red-Yellow Spark: Signals a weak or faulty spark that needs attention.
This immediate visual feedback helps you identify issues like fouled plugs or failing coils instantly.
Simple 3-Step Setup & Adjustable Testing
No complex wiring or training required. The tool is designed for quick deployment directly on the engine:
- Ground It: Attach the alligator clip to the engine cylinder block.
- Connect: Insert the brass connector into the high-voltage ignition wire.
- Test: Start the engine and observe the spark through the window.
Additionally, the adjustable screw mechanism allows you to modify the internal electrode gap, letting you simulate different conditions and test the maximum capability of your ignition coil.
