Description Diagnose ignition troubles instantly with this premium Car Spark Plug and Ignition Coil Tester. Engineered for safe, fast, and highly accurate troubleshooting, this essential automotive diagnostic tool lets you check the health of your vehicle's ignition system without pulling out the spark plug. By completing the circuit between the spark plug and the plug wire, the inline tester visually reveals if your ignition system is delivering a strong, healthy spark or failing altogether. Housed in a heavy-duty, insulated rubber boot for absolute safety against electrical shocks, this tester is a vital addition to any garage or home mechanic's diagnostic kit.

Key Features

• Instant Visual Testing: Built-in high-intensity neon indicator flash bulb lights up brightly to confirm a healthy electrical spark current at a glance.

• Heavy-Duty Shock Protection: Wrapped in a thick, premium insulated rubber protective sleeve to eliminate electrical leakage and protect the user from high-voltage shocks.

• Universal Dual-Voltage Support: Designed to work flawlessly on both 6V and 12V electrical ignition systems, offering versatile performance across multiple vehicles.

• Flexible Copper Core Lead: Features a highly conductive, flexible internal copper wire that resists bending fatigue and withstands heat from hot engine blocks.

• Quick Inline Connection: Simply hook the metal end over the spark plug tip and slide the tester boot onto your vehicle's ignition wire for an instant reading.

Ideal For

• Misfire Diagnostics: Quickly tracking down bad ignition coils, broken spark plug leads, or fouled plugs causing engine stutters and rough idling.

• Multi-Vehicle Use: Essential tool for diagnosing cars, vans, SUVs, motorcycles, lawnmowers, chain saws, and small marine boat engines.

• Mobile Mechanics & DIY Garage: A fast, low-cost diagnostic tool that saves time and money by preventing you from replacing perfectly good ignition parts.

How to Use

1. Turn off your engine and carefully detach the ignition wire lead from the spark plug terminal.

2. Push the black, flexible rubber female boot of the tester firmly onto the top of the spark plug.

3. Attach the metal male plug end of the tester into the vehicle's original ignition wire sleeve.

4. Turn over the engine. If the ignition circuit is working properly, the bulb inside the clear window will flash brightly. If it remains dim or dark, your spark is weak or missing.
