Weekly Waveform 4 - AC coupling starting and charging

This weeks assignment is to use AC coupling on our starter system and charging system. We use AC coupling to remove the DC voltage from our waveform (normally 12 volts) so we can focus on what's happening on the surface of the waveform. We can change our scale from 20v down to 1volt or even less. This enhances our accuracy and the size of waveform drastically but removed our ability to measure the voltage on the trace compared to battery negative.
