What are the sections of a secondary ignition scope pattern?

A secondary ignition scope pattern typically consists of three main sections: the initial rise, the plateau, and the fall. The initial rise represents the voltage buildup as the ignition coil charges, while the plateau indicates the steady-state voltage during the spark discharge. Finally, the fall section shows the rapid decline in voltage as the spark plugs extinguish. Analyzing these sections helps diagnose ignition system performance and identify potential issues.
