Megger an ignition coil (helpfull or harmfull)?
(OP)
Would it be or any benefit to megger an ignition coil to test the condition of the windings?
The step up voltage would be very large therefore I would guess that it would only be done from high output to the low voltage input.
Would such a test be beneficial to evaluate the condition of an ignition coil or just a waste of time?

Don't know what connecting a 500V megger across the HV winding would prove one way or the other apart from simple continuity of the HV winding.

To think of it now after reading the replies it was a dumb question.
I was just looking for a more sure way to test an ignition coil when they get hot. I had figured that they must internally short when the saturation time is too long. Or when the insulation gets old and weak.
But now to think about it, where would the current go.
I should have asked what happens to the ignition coil when it over heats and stops working until it is cool again.
