Getting 2 different readings when secondary coil is shorted or open when using an LCR meter to measure primary capacitance of an HEI ignition coil. This parameter is not provided by the manufacturer. There are 2 windings, primary and secondary are not connected to each other as in other automotive ignition coils.
Trying to input measurements into a SPICE simulation but it would be far more accurate with the coils parasitic properties. When secondary is open reading is ~645uF then when secondary is shorted reading is ~430uF. Which is the correct capacitance value of the primary coil?
