Driving your Mercury will let you experience different problems and it can start upon sitting on your vehicle's driver seat. Some vehicles are really difficult to start, but it will, be made easier if you know what and where the problem is. Starting any vehicle requires a good and efficient ignition system. Such system is composed of different devices that help in the performance of a good ignition process. The ignition system is composed of the spark plug, spark plug wires, terminals, and others. And for your Mercury, the main component of such system is the Mercury ignition coil. The ignition coil is considered as the heart of the ignition system. This component is a pulse transformer as it receives small amount of electrical voltage from the battery. It is also responsible for transforming such small amount of voltage into a big jolt and sends it into the spark plug through the distributor. The coil is made of two windings and a core of iron and as the electricity travels through the primary windings, it produces a magnetic field in the coil. Through this process, it can be said that the ignition system cannot perform its function well without an efficient and durable ignition coil as it is the component that supplies electricity to the ignition components. The coil can be affected if you are driving through rough roads and when it happens, you will experience poor ignition performance and it will be a sign for you to replace this ignition component.
