Inline Spark Plug Tester for Automotive, Motorcycle, and Lawn Mower Engines

Product Specifications: The product is made of stainless steel and plastic, with a black color.

Using the Tutorial: 1. Turn off the engine and remove the spark plug wire. 2. Connect the black connector to the spark plug. 3. Insert the test metal end into the spark plug wire and try to start the engine. 4. If the bulb will flicker, the ignition circuit is complete.

Hint: If you do not get correct results in bright lighting conditions, try again in a less bright environment. If the ignition spark is sent to the cylinder, the lamp in the tester will glow and reflect the spark. The brightness of the lamp indicates the number of sparks, and the pulse and brightness are related.

High-Quality Material: This product adopts a high-quality electroplating shaft, which is rust and corrosion-resistant. The rubber protective sheath, high-temperature resistant wire, and tightly bonded connector provide excellent insulation. The lamp shell is made of environment-friendly acetate fiber plastic, which has no impact on the low-temperature environment.

Quick Problem Diagnosis: The spark tester is an excellent tool for quickly and easily diagnosing ignition and finding engine problems and defects. It can also check spark plug connections, contact points, cables, and other potential issues.

Easy to Use: The product's indicator light display helps determine which cylinder is causing the problem and trace the issue to its root cause.

If the ignition circuit has been completed, the bulb will flash when the engine is started.
