Basics of a Vehicle’s Electrical System

Your vehicle’s electrical system is complex and essential. It starts the car, charges the battery, runs the lights, powers the windows up and down, and runs the systems of an electrified vehicle. Before we discuss common electrical problems and diagnoses, let’s delve into the basic components of your vehicle’s electrical system.

Battery

The battery stores power to start the vehicle. It fires up the ignition system to create combustion and start the engine. A healthy battery is essential to turn the engine over.

Starter

While the battery stores power, the starter gets the engine going. The starter motor gets power from the battery and engages the flywheel and crankshaft to turn the engine over.

Alternator

When you’re running the engine, the alternator creates power to keep the battery charged. You can start the engine with a faulty alternator if the battery is full, but it won’t run for long because it won’t recharge.

Wiring

The wiring system lets the electrical components communicate with each other. There are lots of electrical wires throughout the car, including the headlights, taillights, infotainment system, and windshield wipers. Faulty wiring can cause erratic behavior within the electrical system and may be a potential fire hazard.

Fuses

The fuses protect against damage to the wiring and electrical system by shutting off power to a faulty component. A blown fuse indicates an electrical problem.

Identifying Common Vehicle Electrical Problems

Electrical problems in cars generally require professional technicians with diagnostic tools to identify the issue. If you notice any signs of an electrical issue, take your vehicle to a local auto repair shop or our dealership for repairs.

Dim or Flickering Lights

If you notice any dimming or flickering of your headlights or interior lights, it could be a sign of a weak battery or a faulty alternator.

Malfunctioning Accessories

Are your power windows slow to go up or down? Is the radio or infotainment system acting oddly? If so, you may have a faulty battery or an issue with the wiring system.

Blown Fuses

If you have accessories that suddenly stop working, you may find that a fuse has blown to prevent further damage to the electrical system. You can sometimes replace a blown fuse and not experience the problem again. However, if you experience consistent fuse issues, a problem in the electrical system is likely.

Dead Battery

The alternator charges the battery while you drive. The battery is dead if your engine doesn’t start. This may be because it’s not getting a charge from the alternator or the cells inside the battery are defective.

Strange or Burning Odors

Burning odors from the engine compartment or anywhere in your vehicle are never a good sign. Faulty electrical wiring can cause a spark creating a burning smell. This situation needs immediate attention to prevent further damage and ensure your safety.

Trouble Starting the Engine

When the starter motor fails, it can’t send power to the battery to start the engine. With a faulty starter motor, you’ll notice a clicking noise when you turn the key or have no response.

Preventive Measures and Maintenance Tips

Regular maintenance is the best prevention for electrical problems in your vehicle. When you bring your car, truck, or SUV to us for maintenance, we’ll perform a multipoint inspection to ensure all systems are in good working order.

You can also regularly inspect the battery, terminals, and cables. While you have the hood of your Chevrolet up, check for any leaking fluids and frayed wires, hoses, or belts. If you see corrosion around the terminals or fraying of the battery cables, you may need a new battery. You can also check and replace any burnt light bulbs, test the battery voltage with a multimeter, and clean the battery terminals.

How To Diagnose Electrical Problems in Vehicles

Diagnosing car electrical problems beyond simple DIY tasks requires specific tools and the knowledge to understand their results. If you use a multimeter, read the instructions carefully so you know how to use it and how to interpret the information it provides. You can then share this information with our service technicians to help pinpoint the problem.

When To Seek Professional Help

The electrical system in your vehicle is complex and needs professional service technicians to diagnose and repair it. The components of the system rely on each other to perform properly, so you may experience issues throughout the system if you don’t address a problem as soon as possible.

If your vehicle is experiencing electrical problems, bring it to our Crestview dealership.
