Does the msd ignition replace coil and is it end all cure of an circuit problems?

An MSD ignition system does not replace the coil, but works in conjunction with it to improve the overall performance of the ignition system. It consists of several components, including a high-voltage coil, an ignition control module, and spark plug wires. The ignition control module is the brain of the system and monitors factors such as engine speed and load to determine the optimal timing for spark delivery. It then delivers a high-voltage signal to the coil, which creates a spark plug voltage of up to 50,000 volts. This results in a hotter spark that ignites the air-fuel mixture in the engine with greater efficiency and produces a more complete combustion. However, it's important to note that while an MSD ignition system can enhance the performance of the ignition system, it is not an end-all cure for all circuit problems in a vehicle. It only addresses issues related to the ignition system, such as ignition timing, spark strength, and overall performance. It does not fix other electrical or mechanical problems within the vehicle's electrical system, such as faults in wiring, switches, sensors, or any other components that are unrelated to the ignition system.
