Ignition Coil Testing

The unit is to help me better study dwell and spark duration at higher RPM. Plug gap, and cylinder pressure plays a part, since they raise the voltage, increasing energy pulled out of coil. The tight plug gap is keeping the energy low, for safety. Monitoring of the current, and controlling the coil charge is done by modern ECU's. I may play with that some, on a more powerful platform.

This is a cheap way to make sparks, but care must be taken, or it could kill PC and make smoke. Part of this project, was to see if Del would get interested. He has, so I am in the process of documenting my work, so he and other brave souls can play too.
