5 Things Everyone Should Know About Car Electrical System

The car is becoming more and more like a computer, which makes it harder to understand. You may have noticed that your car has some very specific quirks, such as how it needs a specific key or won't start if the battery is too low. These are all things that can be easily fixed with some basic knowledge of the electrical system in a car.

The following 5 things are very important to understand the electric car:

1. An engine needs a lot of current to start

You've probably heard the expression, “The starter motor is the most important part of a car.” It's true—the starter motor is what starts your engine when you turn the ignition. When it comes to starting your car, this is one part that you don't want to mess with or replace without a professional mechanic's help (or at least some knowledge of how to do it yourself).

The first thing that needs to happen for an engine to turn over and start is for electricity to flow through both terminals on the battery into its posts on either side of its case; then, once enough current has flowed through those connections, it can travel through wires leading from there into other parts of your car's electrical system—and eventually into something called an alternator which provides power directly back out onto those same wires again so they're ready for another go-round next time around.

2. Electricity can be deadly

Electricity is a powerful force. That's why your car's electrical system is designed to protect you from any possible dangers that might arise as a result of it. For example, the battery terminals are connected to each other through a switch that prevents excess electricity from escaping into the air when you're not using the car. This way, if you accidentally put your finger on one terminal while touching something else (like another metal object), there won't be enough power to give yourself an electric shock—but it can still hurt!

If you do happen to touch both terminals at once, it will cause enough current flow through your body for you feel its effects instantly: tingling in your fingers or toes; muscle spasms; nausea or dizziness; and even unconsciousness or death if sustained long enough (which would obviously be really bad).

And speaking of things that could kill us: no smoking near cars!

3. Keeping the battery clean is very important

 It has to be cleaned at least once per year, and more often if you see any corrosion or build-up on the terminals or case.

Cleaning the battery terminals can be done by removing them from the posts (the metal parts that attach to your car) using a wrench and then wiping them down with a cloth or towel moistened with water and baking soda. Don't use harsh chemicals like bleach or acid cleaners, as these can damage your cell plates. If there's rust built up on your terminal posts, scrape it off gently with a metal brush before applying paste wax for protection and shine.

Cleaning the inside of your car's battery case can also help extend its lifespan by preventing damage from moisture buildup inside it when batteries aren't in use for long periods of time; simply wipe down its interior surfaces with oil-dampened rags after cleaning its terminals so that rust doesn't form again later on due to exposure to air humidity levels rising higher than normal (like during summertime).

Replacing old cables should be done every few years because they'll become brittle over time due to long-term exposure heat generated by turning on lights/radio speakers etc. while driving around town getting groceries. You should definitely not do this yourself, it is best to take the car to a local electrical mechanic in Nerang, because any fault should be prevented or fixed in time.

4. The size of your car battery matters

The size of the battery is measured in ampere hours, volts, cranking amps and cold cranking amps (CCA). Ampere hours indicate how much energy a battery can hold and is usually given as a range, like "60-100Ah." A 40Ah AGM battery will give you about 40 x 1 hour = 40 hours of use before needing to be recharged. Most people think that this means that it can power their car for 40 hours but that’s not really true because most cars have an alternator which pumps energy back into your electrical system when the engine isn't running.

Voltage is what gives us voltage drops when we start our engines; by creating a lower load on your alternator as it charges up over time helps keep things cool under the hood as well as extending its life span drastically! If you have higher amperage needs then you'll want something bigger than 60Ah but if they’re not too high then go with something smaller unless style is more important than function (which sometimes happens!)

5. An alternator belt is an important part of this process

An alternator belt is an important part of this process, because it connects the alternator to the crankshaft. The alternator belt is a rubber belt that provides a consistent power source for your car's electrical system.

If you have a car with manual transmission and no air conditioning, you may be able to replace your own belts. If you have an automatic transmission with air conditioning, then you will need to take it to a mechanic to be replaced or adjusted.

We hope this article has helped you understand the basics of car electrical systems. From the importance of keeping your battery clean to understanding how much power your car needs and why, it’s important that everyone knows these facts. Electrical systems can be dangerous and complicated, but if you know what is going on inside your car then you can avoid problems and feel confident when driving! Listen to our advice and be safe on the road!
