To allow the ignition system to function, there must be spark that can ignite the air and fuel in the engine of your vehicle to begin. The spark is produced by the ignition coil which creates a magnetic field around the rotor when current passes through it. The magnetic field is created when the rotor turns. This creates the ignition spark. This spark then turns the pistons of your engine, firing them up and allowing it to get going.
Your ignition switch controls the electrical current that runs through the primary and secondary circuits of your ignition system. When the switch is in the "on" position the battery sends low voltage current through the primary coil's windings and then through the breakers. This creates a magnetic field that can ignite spark plugs, and spin the rotor.
When the ignition switch is set to'start' the primary and secondary circuits are closed. As the rotor and distributor cap terminals rotate, the electrical connection between them is broken and stops the secondary flow and closes the primary circuit. This causes the breaker points to close and create sparks at the spark plug, which then ignites the engine in just a few seconds.
