Ignition coil oscillation:
Observe at least two oscillation waveforms after the combustion line,
which will be better if more than three oscillation waveforms, as it
represents the ignition coil and capacitor (on Platinum or ignition
system) are normal.
Primary voltage analysis
According to the faulty primary voltage waveform collected by the
ignition analysis, the related components and mechanical equipment
status of ignition system electrical circuit can be analyzed, which
provides a reliable basis for the adjustment and maintenance of
power circuit to avoid the blind demolition.
The waveform shown on Fig. 4-13, appears a lot of clutter on the
contact break point, which is obviously caused by the serious
erosion on contact break point. It can be verified via burnishing the
contact or changing the circuit breaker.
Fig 4-13
For the primary voltage waveform shown on Fig. 4-14, the damped
attenuation cycles obviously reduced on the spark period, the
