As basic as I can describe it: The points are a switch making and breaking which causes a pulsating current flow through the primary side of the coil. This current flow creates a magnetic field which induces a voltage into the coil secondary windings. Because of the ratio of windings of the primary and secondary sides of the coil, a small voltage (pulsating 12 volts DC) becomes a high voltage in the secondary. Without the opening and closing of the points, there would be only the initial spike of voltage. It is the opening and closing of the points repeatedly that makes this work. The condensor is wired across the points to reduce the arcing that would occur as the points open under load. The current flows into the capacitor instead of across the point gap.
