Rdxcv Inline Spark Plug Tester, Straight Boot Car Armature Diagnostic Detector Pick Up Coil Checker, Internal & External Engine Ignition Tester for Cars Motorcycles Automobiles

• Practical Function: This engine ignition tester provides quick diagnostics for ignition systems, checking engine faults while identifying issues in cables or contact points. It can shorten troubleshooting time and help maintain engine performance effectively in routine service tasks
• Clear Indication: This spark plug checker features a built-in indicator light that shows ignition status clearly, which makes each diagnosis more direct. The light flashes brightly when the ignition system works normally, and it becomes weak when an ignition circuit fault appears
• Quality Material: Made from premium plastic, this tester's housing offers strong wear resistance and insulation to promote safe operation. Its internal copper wire delivers excellent conductivity, and the metal probe provides high thermal stability that avoids deformation for accurate readings
• Wide Application: This inline tester supports spark-plug engines of various vehicles, such as cars, trucks, and motorcycles, for both daily checks and fault diagnostics. It provides steady detection results in common service tasks, meeting the needs of ignition-system testing
• Easy to Use: First, turn off the engine and remove the spark plug coil. Then, attach the tester's black boot to the spark plug and insert the probe into the spark plug coil. Finally, start the engine and watch the indicator light—if the ignition wire is intact, the light will flash
