The secret to being able to capture and analyze secondary ignition waveforms is understanding what is happening in the coil and at the spark plug and how the scope measures and graphs the voltages and ignition event.
Andrew Markel discusses how you can verify that a waveform you have captured is correct for the vehicle.
Can every tech in your shop analyze and diagnose vehicles in 15 minutes or less? Do you know how to analyze amperage waveforms captured with your DSO and low-amp current probe to monitor electrical current through wires? Take our quick quiz to improve your accuracy and help cut your diagnostic time.
