Modern Vehicles Rely on Electrical Systems

Over the decades, cars and trucks have become more and more reliant on electrical systems. From interior infotainment systems to the modules found throughout your vehicle, controlling everything from engine management to suspension stiffness and all wheel drive systems, nearly every part of your car has some reliance on electrical systems.

While the technology has come a long way, the complexity of modern vehicles makes diagnosing electrical problems difficult. While a problem can be as simple as a dead battery, it can take a significant amount of diagnostic work to track down the root cause of that dead battery.

Electrical problems in your vehicle can cause a range of strange behaviors like dim lights, trouble starting, lights on the dashboard, and more.

Common Electrical System Failures

While not an all inclusive list, here are some common failures points on the electrical systems of modern vehicles.

Battery

The battery, along with the alternator, are the heart of the electrical system. The Battery is responsible for providing enough amperage to start the engine when you turn the key. Car batteries are large and can last for years before needing to be replaced.

The battery can be drained, leaving the headlights on, or by something like a parasitic draw, which is a problem that continues to drain the battery when the vehicle is off. Checking the battery is a good first place to start when there is a suspected electrical issue.

Alternator

The alternator is an electrical generator that takes mechanical energy from the engine and converts it to electrical energy. When your car or truck is running, the alternator keeps the battery charged and supplies electricity to other systems throughout the car.

A failing alternator can cause a host of issues like weak lights and a dead battery, in addition to squealing sounds coming from the engine bay.

Fuses

Your vehicle has lots of fuses that help protect electrical components. A fuse blows in response to an issue somewhere in the electrical system like a short. While fuses are inexpensive and easy to replace, if the root cause is not addressed, the fuse will likely blow again. Symptoms of a blown fuse can vary depending on what system it’s a part of.

Modules

Modules are computers responsible for controlling entire systems in your vehicle. Most modern cars have several modules, including the ECU (Engine Control Unit), TCU (Transmission Control Unit), BCM (Body Control Module), and ABS (Antilock Braking System) Module.

A module failure, like other electrical problems, can cause a range of issues that impact everything from interior function to driveability. Module failures will often cause a warning light to illuminate.

Relay Failure

A relay is a switch, allowing for the operation of components like turn signals, fuel pumps, and headlights. A failed relay can lead to a range of problems depending on the system it’s tied to.

For example, a bad fuel pump relay can make your car hard to start or stall out, while a turn signal or hazard relay will prevent your turn signals from blinking.

Wires

All the electrical components in your vehicle are connected by wires. Over time, wires can become damaged, leading to weak or dead connections. Tracking down bad wires can be very time-consuming.

Call or Schedule Now!

Though a bad battery is the most frequent culprit of why a car isn’t starting, there’s a chance an issue with the electrical system in your car could be the true problem. Dim headlights and/or brake lights can also indicate issues with the electrical system, potentially with the alternator. A complete auto diagnostic from Arvada Square Auto can pinpoint the source of your electrical issue, and then perform high-quality repair services to return your vehicle to operating as it should!
