Re: Red OMC coils

Seems if the module is using a transistor the polarity of the magnet and wrapping, voltage induced would make a difference depending on which leg the leads are attached to the transistor. But transistors only travel one direction of current flow, then the difference between pnp and npn would make a difference but still current flows from collector to emitter via modulation of the internal film. That still doesnt really explain why the coil wrapping has to be specific for the module. Thats an oddity unless the magneticism has an affect on the radio frequency induced on the coil via module pulsation. Similar to emp on an automobile, remember the old days when they used a capacitor or something similar in the alternator circuit to stop radio interference, that also helped keep early voltage regulators an distributor modules from frying as well.
