Battery
The battery is the heart of the electrical system. It provides the power to start the engine, and it also powers all of the electrical components of the car when the engine is not running. The battery section of the 2018 Kia Optima wiring diagram shows how the battery is connected to the rest of the electrical system.
The battery cables are shown in the diagram as thick lines. The positive cable is usually red, and the negative cable is usually black. The battery section also shows the location of the battery in the car.
Starting System
The starting system is what gets the engine running. The starter motor is connected to the battery, and it uses the power from the battery to crank the engine. The starting system section of the 2018 Kia Optima wiring diagram shows how the starter motor is connected to the battery and the ignition switch.
The starting system also includes a relay that controls the flow of power between the battery and the starter motor. The relay is shown in the diagram as a small box with wires coming out of it.
Charging System
The charging system is responsible for keeping the battery charged while the engine is running. The alternator is connected to the engine, and it generates electricity as the engine turns. The charging system section of the 2018 Kia Optima wiring diagram shows how the alternator is connected to the battery and the rest of the electrical system.
The charging system also includes a voltage regulator that controls the amount of power that the alternator generates. The voltage regulator is shown in the diagram as a small box with wires coming out of it.
Ignition System
The ignition system is responsible for starting the engine and keeping it running. The ignition switch is connected to the starter motor and the fuel injectors, and it controls when and how much fuel is injected into the engine. The ignition system section of the 2018 Kia Optima wiring diagram shows how the ignition switch is connected to the rest of the electrical system.
The ignition system also includes a spark plug that ignites the fuel in the engine. The spark plug is shown in the diagram as a small box with wires coming out of it.
Lamps and Lights
