The modern automotive engine electrical system is composed of different electrical parts that make, store, and distribute electricity to other auto parts that need electrical power. The first major part is the battery; it's used to store power used for starting the engine and running electrical devices such as the radio, digital clock, lights, air conditioning, and car alarm. Make sure the battery has enough juice to power the electrical system by using a voltage meter.
Working together with the battery and another essential part of engine electricals, the starter motor is used to fire up the engine. This part consists of a DC electric motor and a starter solenoid that's usually attached to the motor. A high current is required by the starter motor to successfully start the engine; that's why the motor is connected to the battery with large electrical cables. Working like an electric switch, the starter solenoid, when activated, closes the circuit and connects the starter motor to the battery. During this time, the solenoid also pushes the starter gear forward to join with the engine's flywheel.
Engine electricals won't be complete without aid from the alternator. It's a type of generator that transforms mechanical energy from the engine into electrical energy. The alternator plays an important role because it supplies a steady amount of power to most of the electrical parts in the vehicle. Alternating current, rather than direct current, is the type of electricity that gets produced by the alternator. The movement of the crankshaft is converted into electricity to power the various electrical features of a vehicle.
Because the car engine electrical system is composed of lots of wires and wiring harnesses, this elaborate system should always be maintained periodically. To check whether or not the wiring is able to deliver electricity to a specific part, use a wire diagram and test light. Safeguarding these electrical circuits are fuses, which are designed to stop electrical flow when there's a power overload or short circuit. A blown fuse should be replaced as soon as possible. Otherwise, additional fuses could be blown. By making sure that proper maintenance is given to your vehicle's electrical system, you're saving money from costlier repairs down the road.
The engine electrical system works hand in hand with other automotive systems to help your vehicle function properly.
