The Ignition SystemThe primary circuit consists of an ignition switch, ballast resistor, some type of off/on switch , ( in the older cars a set of breaker points) , which is usually inside a distributor, an ignition coil and the connecting wires. The purpose of the primary circuit is to allow low A Short Course on Ignition SystemsThe voltage that is available to the spark plug is somewhere between 20,000 volts and 50,000 volts or better. The job of the ignition system is to produce that high voltage from a 12 volt source and get it to each cylinder in a specific order, at exactly the right What is a Distributor?A distributor is an ignition component that, as its name implies, distributes spark to each of the engine’s spark plugs. Voltage is sent from the ignition coil to the distributor cap via a spark plug wire. That voltage then travels from the cap’s center terminal to the rotor located inside
