Ignition Coil Testing

I find it easy to spend money on electronics parts. I will check my mail.

Last night I did a few minutes of work to make a low voltage sine wave with timer0, and PWM, so I can drive the coil primary, then measure the secondary, to determine the turns ratio. By doing that it is easier and safer thsn trying to measure the secondary for spark voltage. I also bought a $25 2KVscope probe for better measurements.
