COP Ignition Coil System Maintenance Tester Tool 1. Power supply: button battery 2. Suitable for maintenance of vehicles or other lines 3. The ignition coil test tool is used to quickly determine whether the COP generates the correct voltage and arc duration 4. A handheld ignition system that can easily and quickly detect whether the ignition coil and spark plug in the COP type (ignition coil-spark plug integrated) ignition system are igniting normally 5. It can be triggered by the signal of the ignition secondary coil 6. When the signal is received, it can detect whether the ignition voltage (combustion voltage or peak voltage) and combustion time (spark duration) of the COP are normal 7. When the ignition voltage is normal, the red strobe LED flashes, and when the flashover duration is normal, the green strobe LED flashes 8. No reflection or continuous reflection indicates that the ignition voltage of the ignition coil is insufficient 9. The use of the ignition coil tester is relatively simple. Just start the work at the test point above the ignition coil induction head and judge the working status of the ignition coil according to the ignition result
