There has been a transition in automobile electrical systems over a decade. Previously electrical systems in a vehicle comprised of basic wirings, which were meant to distribute power to specific parts of the vehicle. Wires, relays, controlled motors and switches were used as components to provide power in various parts of the vehicle. In comparison to that, today’s automobile electrical system includes alternators, actuators, sensors, starter solenoid, oxygen sensors, battery, starter drive, generator, high power electrical systems and other components. Among these, battery, starter and alternator are the key electrical components. The alternator provides energy to the battery by which the battery transfers power to the starter to ignite the engine. The battery provides electrical current to the car till the time vehicle starts. This includes the flow of current to fuel systems and ignition, which allows proper combustion that is necessary for the functioning of the engine. The bat
