Example of coil diagram for independent ignition system

For the fault detection of the ignition system, the best way is to use Pico automotive oscilloscope (Guangzhou Hongke is the general agent of British Pico company) to detect its primary and secondary ignition pulses, to analyze its actual working condition, and to judge whether it is faulty or not.

Because the COP coil is well wrapped, it is not easy to access its secondary circuit. In order to detect the secondary ignition waveform of COP more conveniently, Guangzhou Hongke provides a fast and convenient solution, COP independent ignition probe. The probe is a capacitive inductive type, which can sense the ignition voltage by placing it directly on the COP coil. The connection diagram for detecting COP coil high voltage ignition waveform with PicoScope is as follows:

The secondary ignition signal waveform is as follows:
