How would you know if your CDI is dying?
Are there symptoms apparent which would be a clue that it is time to replace the unit?
Is there apparent symptoms while driving the car that would lead one to believe the CDI was dying? ( I am assuming that if one is driving and the CDI unit is faulty or dies? )

The reason I ask is, I have observed that the "whine" is slowly getting lower and lower with one of my cars. In other words, there was a time when I would be in the driver's seat with windows up and I could hear the sound of the CDI when the key was turned to the "ON" position (ignition switch).
But, as of late, for me to hear anything I have to turn the key to "ON" position and then walk to the back of the car to hear the high-pitched sound of the CDI.

Appreciate your thoughts on this "dumb" question.
