The coil is responsible for generating high voltage electricity, which is then sent to the distributor. The distributor contains a rotor that spins inside it, distributing the voltage to the correct spark plug at the right time. This sparks the fuel and air mixture in the combustion chamber. Before diving into the wiring process, it's important to understand the basic components of an ignition coil distributor system. Incorrect configuration of these can lead to misfires, poor. Modern vehicles don't run using distributors, but you can find them in classic cars built in the 80s and 90s.
