I have a tiny PCB-mounted, e-core, step-up transformer (probably 1:200 or 1:250) that is used in a small sparking circuit (images below). It uses a simple, transistor-induced square wave to turn a now-oscillating, battery-powered 3VDC circuit into a higher voltage AC-like wave on the secondary "coil" which feeds a 0.22uF capacitor by way of a standard diode.
There is no continuity between the leads of the secondary coil - but the circuit works as intended...seemingly indicating a) the intentional use of open-winding coils...or b) that the excessive length of thin-gauge coil wire somehow does not produce a continuity reading on the meter. Thoughts?
