A vehicle electrical system consists of 5 main parts:
- Battery
- Starter
- Solenoid/Relay
- Alternator
- Fuse Box
1. Battery
The battery stores the power needed to start your vehicle. This energy also fuels things like the radio, clock, and car alarm when the engine is not running. McWhorter also offers battery repairs outside of electrical issues.
2. Alternator
The alternator creates the electricity to maintain the stored power create by the battery. This helps to run electrical devices like the ignition and engine controls. The alternator is powered by a belt connected to the engine.
3. Starter
The starter is the most crucial component in your car's electrical system. Though it is only used a few times during a typical day, the starter requires the most power out of the whole electrical system. The starter utilizes the flywheel to turn the engine's crankshaft. This action starts the combustion process.
4. Solenoid/Relay
Once combustion begins, compression is created in the cylinders. This process sends voltage from the battery to the starter, and the voltage is administered to the starter by the solenoid (or relay). An ignition switch controls the starter solenoid, and the solenoid activates the starter motor. The starter motor cranks the engine until it catches and the car starts.
5. Fuse Box
Every electrical component in your vehicle is connected to the fuse box by wires or wiring harnesses. Inside the fuse box there are many fuses that protect your car from short circuits or power overloads that could potentially cause damage or even start a fire. A temporary power overload can cause a fuse to blow, and then when that happens, it needs to be replaced.
