Auto Ignition Coil Tester - Professional Diagnostic Tool for Car Coil on Plug System | Home & Lab Use | Perfect for Mechanics & DIY Car Maintenance

Specification: Item Type: Ignition Coil Tester Material: ABS Battery: CR2032 button battery, 120mAh (built-in) How to Use: 1. Correctly connect the connector and sensor head to the tester 2. The induction head is aligned with the ignition coil to start working, and the working status of the ignition coil is judged according to the result of lighting Test Results: Red LED Light Consistent, steady flashing and beeping indicates the COP is producing the correct amount of voltage. No response or an inconsistent response indicates the COP is NOT producing the correct amount of voltage. This may be caused by one of the following: 1.Fouled spark plug, or incorrect gaps 2.Damaged/corroded wires or connectors 3.Faulty coil or PCM Green LED light Consistent and steady flashing indicates the duration of the arc is correct. No response or an inconsistent response indicates the duration of the arc is NOT correct. This may be caused by one of the following: 1.Shorted windings inside the coil 2. Resistance or bad connections in the 3. primary / secondary connections 4. Faulty coil Package List: 1 x Ignition Coil Tester 1 x Adapter Lever 1 x Sensor 1 x Manual 1 x Storage Bag

PROFESSIONAL PERFORMANCE: Hand‑held coil on plug fast ignition tester, battery powered, with stable and professional performance.

EASY TO USE: Once the signal is received, the tester will determine whether the COP produces the correct amount of voltage and arc duration.

LED INDICATOR: If the voltage is correct, the tester will beep and the red LED indicator will flash; if the arc duration is correct, the green LED will also flash.

APPLY TO: The ignition coil checker is specially designed to easily and quickly determine whether the COP produces the proper spark for the plug.

EASY TO INSTALL: Easy to install and replace, no extra parts are needed, you can easily install this coil on plug quick tester, save your time and energy.
