Spark Plugs - Secondary Ignition Waveform Analysis

Secondary ignition waveforms can be a mystery. In this Shop Squad video, we look at how the waveform is captured and interpreted by a technician. The video explains the different segments of the waveform and how they depict what is happening between the electrodes of the spark plug.
