The system worked by charging the coil with 6 to 8 volts when the points are closed. When the points open it collapses the magnetic field that was created in the coil. this creates 20,000 volts in the Secondary coil and that goes to the spark plugs.
But it also creates 300 volts in the primary coil that is attached to the points. This has to go someplace and it is strong enough to jump the point opening this will burn the points very, very fast. So a condenser (Capacitor) is put into the system at this point to catch the 300 volts and bleed it off harmlessly into the ground system.
Works kind of like a big hole in the ground to catch the extra water from a spill. When it does not work your points will burn out immediately. One big Poof.
