Ignition Coil Spark Tester with LED Display, Non-Contact Electronic Fault Detector Pen for Car Engine Systems

Ignition Coil Spark Tester with LED Display, Non-Contact Electronic Fault Detector Pen for Car Engine Systems

• Advanced Non-Contact Diagnosis: Utilizing German-engineered sensors, this detector analyzes automotive electronic signals without dismantling parts. Results are instantly displayed via multi-color LED indicators and an audible beeper for real-time fault assessment
• Intuitive Audio-Visual Alerts: A continuous beep confirms component integrity (e.g., no short circuits or disconnections), while silence or irregular beeping indicates malfunctions. Combined with LED color codes (e.g., blue for normal), it simplifies diagnostics for beginners and professionals alike
• Enhanced Durability & Safety: Operate in well-ventilated areas to avoid engine exhaust interference. Designed with heat-resistant materials, it protects against accidental contact with moving parts and high-temperature components, ensuring equipment longevity
• Broad Vehicle Compatibility: Tests 12V gasoline systems including: Ignition coils (traditional/double/single-spark) Fuel injectors, solenoid valves, relays Generators, cooling fans, Hall sensors Spark plugs (via adjustable spark strength simulation)
• Dual-Mode Precision Testing Features two detection modes: → Standard mode: Climate-triggered LED/prompt for optimal engine performance. → High-sensitivity mode: Magnetic-field-optimized antenna for tracing live wires and EMI faults. Ideal for both routine checks and complex electromagnetic diagnostics
