Picoscope fundamentals - ignition waveform analysis

This is part 2 of an introductory video series describing how to use a labscope for automotive diagnosis. In this chapter we go through the fundamentals of a traditional distributor based ignition system, with a demonstration of secondary waveforms using a Picoscope in the 1998 Dodge Ram. To consolidate knowledge we play a brief matching game, trying to match the secondary waveform with various common ignition faults.

This demonstration is an amateur effort, done in good faith but with no guarantees as to accuracy or safety. Automotive diagnostics will always come with inherent risks. Any misadventure you encounter if you decide to repair your vehicle is your responsibility.
