How To Check Your Basic Electrical Systems

October 2, 2020 4:09 pm Published by

Cars have become immensely more complicated over the past few decades. From extremely complicated computers to sensors for everything from fuel mixture to tire air pressure, your vehicle is packed with wiring, electrical systems, and complicated relays. Every single one of these systems relies on the electrical system of your car to function. Your electrical system is run and charged by a few crucial components, and if any of those systems fail, you could find yourself in a sticky situation. The most important thing that your electrical system does is provide the energy to start your car through your sparkplugs. You can easily check and improve your electrical systems, but first, you need to understand what each component does and the signs that it could be failing. If you would like to learn more about your vehicle’s electrical system and how to fix this system yourself come into your local U Pull And Pay today.

Alternator

One of the most crucial components of your car’s electrical system is your alternator. Your alternator is essentially a small generator that produces alternating current, which is then immediately converted into direct current in order to work with your vehicles 12-volt DC system. Alternators are powered by a belt system that utilizes your engine’s energy and movement to passively generate the current needed to charge your system. There are a few signs that your alternator could be on its way out or starting to fail. Most vehicles have a sensor in the alternator itself and will display a warning light on your dashboard. Other signs of a failing alternator include dim headlights and interior lights, electrical failures, stalls, and difficulties starting your vehicle.

Regulator

Electricity is a strange force. Too much of it can fry your system and not enough of it won’t allow your electronics to turn on at all. That is why every electrical system, including the one in your vehicle, requires a regulator in order to ensure that the correct voltage travels through your system. Your regulator ensures that your system is constantly filled with between 13.5 and 14.5 volts. Regulators are generally mounted inside of your alternator, making the two systems easy to swap out together. Regulators are built to stand the test of time, and you will rarely have a problem with your regulator in any noticeable way.

Troubleshooting Tips

If you are noticing any lack of electronic capability in your vehicle, you might want to look into replacing your alternator first, as this repair is one of the more financially reasonable and time-efficient ways to help your electrical system. Make sure that if you are going to replace your alternator that you disconnect the battery first. If your regulator is the issue on the other hand and you are inexperienced at electrical systems, you might want to consider replacing the full alternator instead as you will need to disassemble the alternator in order to access the regulator.
