I have some old ignition coils that I would like to compare. I have set the secondary to resonate with a .47 mf capacitor and these coils will resonate at 50 to 70 hz. The problem is, I can't really compare them as the center frequency is different on each. Is there a way to test their q factor at a certain frequency, say 60 hz, short of substituting in a bunch different caps?
