Primary Ignition vs Secondary Ignition Waveform Notes
The example waveform shows the exact relationship between the ignition’s primary circuit and the secondary output. The primary circuit transfers its characteristics into the secondary through ‘mutual inductance’ and will mirror the primary exactly.
The blue trace shown in the example is the Low Tension (LT) signal, measured from the coil’s negative terminal (marked number 1). The red trace is the High Tension (HT) output voltage measured at the king lead. In the example shown both waveforms show exactly the same burn time of 1.1 milli seconds (ms).
