Like you say the breaker point systems are comprised of four major components.
A source of electronic force(generator, alternator or battery), a switch(the breaker points), a step up transformer(coil) and a contact protection device(capacitor). The fixed side of the points are(usually) the negative most connection in the system. The operating side of the points are connected to one side of the primary winding of the coil. The other end of the coil winding is connected(usually) to the positive side of the system. The capactior is connected across the points. When the point contacts close two things happen; the capacitor is shorted and current flows thru the contacts and coil and establishes an electro-magnetic field in the coil. As the distributer rotates and the point contact opens the magnetic field collapes and induces a field into the secondary winding of the coil and attempts to discharge across the point contact. This is the arc that causes the points to erode. The capacitor(which is not now shorted) begins to charge absorbing most(but not all) of the discharge. The secondary winding is connected, via the large high voltage lead, to the distributer cap. The high voltage lead connects to the rotor. As the rotor turns the pin on the rotor passes by the pins in the cap. These pins connect to the spark plugs. If all the parts are in alignment the plug should receive a momentary pulse of about 10-15k volts.
