With a 2 channels scope ( with internal memory / recording ) it can be investigated .

1st channel connected to the non permanent 12V, second channel connected to the high voltage coil output wire ( through an induction probe ).

With this , it is possible to see if some sparkling event happen or not after you turn off the key.
