How to perform a compression test with a scope (Picoscope)

In this video I will be showing you how to use starter current to determine cylinder compression. First I will show you a known good pattern, then I will simulate a no compression problem in one cylinder by removing a spark plug. Finally, I will show you how to synchronize the starter current waveform with an ignition firing event in order to determine which cylinder in the firing order has the compression problem. Tests shown - cranking compression test with a scope and high amp probe - how to synchro
