| Primary Circuit | A low voltage circuit that is part of the ignition system. |
| Battery | A device containing one or more cells that produce electricity through electrochemical action. |
| Charged | A condition of a battery in which it can produce the highest output of electricity. |
| Ignition Switch | A key operated switch mounted on a steering assembly for connecting/diconnecting power to the ignition & electrical system. |
| Resistor | An electronic device placed in a circuit to lower voltage and current flow. |
| Ignition Coil | An electrical component used to increase battery voltage to fire the spark plugs. |
| Core | The laminated iron center wound with thousands of turns of very fine copper wire. |
| Primary winding | Low voltage winding in a coil. It is made of heavy wire. |
| Secondary Winding | The high voltage winding in a coil made of very fine wire. |
| Magnetic Field | Area encompassed by magnetic lines of force surrounding a magnet. |
| Field Collapse | When the magnetic field created by the primary windings subsides through the secondary windings into the core |
| Self Induction | The creation of voltage in a circuit by varying current in the circuit. |
| Induction | The imparting of electricity to an object by magnet fields. |
| Polarity | The positive or negative terminals of a battery and certain other electrical components. |
| Distributor(1) | Unit designed to open/close the ignition primary circuit mechanically or electrically. |
| Flashover | An arc, or jump, of ignition current across an open space/gap. |
| Contact Points | A simple mechanical method of making / breaking the coil primary circuit. |
| Distributor Cam Lobes | The square-shaped corners on the distributor shaft that cause the breaker arm to move in/out of contact at the points. |
| Dwell | The amount of time the distributor points remain closed between openings. |
| Condenser | (aka:a capacitor)absorbs excess primary current when the contact points are opened. |
| Capacitance | The property of a capacitor or condensor that permits it to receive and retain an electric charge. |
| Ignition Module | An electronic component that controls ignition spark or compression. |
| Magnetic Pickup | A sensor mounted in the distributor which generates alternating current. |
| Reluctor | An elec. ignition component in distributor affixed to distrib. shaft, triggers a magnetic pickup which, then, triggers the control module to fire the coil. |
| Capacitor | An electronic device designed to absorb electrical energy up to a specific level and then release it all at once (unlike a battery). |
