Nowadays, the auto electrical systems of vehicles are getting more complex, predominantly for the reason that modern technology has acquired various means on how to improve these systems for a better performance. However, it is important to note that the electrical systems still feature the same design that it had a few decades back, and the components that comprise it are still the same. If you are not fully knowledgeable on the components that make up your Volkswagen’s systems, you do not have to worry – they are simply the battery, the alternator, and the starter.
The battery is undeniably one of the most essential components of your Volkswagen, because this storage device is responsible for starting the engine and activating the electrical peripherals installed in your vehicle. The battery is composed of six cells of positive and negative lead plates, which are divided by insulators and submerged in electrolytes. Each cell creates 2.1 volts of stored energy, and the chemical reaction formed between the plates and electrolytes generate volatile gases that are released through the battery cover vents. It is imperative that you take proper care of your batteries through conducting regular inspections and cleaning.
The second component of your Volkswagen’s electrical system is the alternator, which generates the electricity used in regulating the battery storage charge and assisting the operation of the electrical accessories such as the ignition and the engine control systems. It creates alternating current (AC) that is eventually converted into 12 volts direct current through the system’s diode bridge. Most alternators make use of internal voltage regulators in controlling the system voltage at around 12.6-14.5 volts. In contradiction to what most people belief, an alternator does not continuously generate electricity, for in actuality, it turns the electricity on and off as the demand increases and decreases.
