Top Car Electrical Problems

February 21, 2022

Modern vehicles rely on computers and electrical components for a variety of vital functions. From transferring power to the engine to operating windows and headlights, it’s crucial for your car’s electrical components to be working properly. When these parts don’t work properly, your vehicle could drive poorly or not at all.

Here are the leading signs that you need auto electric repair.

Faulty battery

This is still the most common electrical problem that drivers face. You put the key in the ignition, but the engine won’t turn on. If you can still use the lights and the other accessories, it means the battery isn’t completely dead yet. Try doing a jump start according to the instructions in your manual. If this doesn’t work, then you may need to have the vehicle towed or have a specialist come to you.

Bad alternator

There comes a time when your car will need alternator replacement. A bad, damaged or otherwise malfunctioning alternator will also prevent the battery from storing an adequate charge. If your car has dim headlights or other signs of electrical malfunction, then a faulty alternator is likely to blame.

Bad battery cables

When you try a jump start and it doesn’t work, it could be because of a faulty alternator, but another possibility is that it’s the battery cables. These are vital for the car’s functioning because they connect the battery to the electrical system. When you have corrosion on the battery terminals, no power will transfer to the vehicle.

The battery fails to charge

If your battery is unable to hold a charge, then it’s time for auto electric repair. Batteries will wear out if you use them for many years.

Damaged spark plugs

Dirty or loose spark plugs will compromise your car’s performance. Signs that this is the case include lurching or rough idling.

Malfunctioning starter or solenoid

The starter or solenoid is responsible for helping the engine turn over. When you attempt to start the car and only hear a series of clicks, that could be because the starter has gone bad. In this case, bring your car to a professional mechanic.

Blown electrical fuses

Consider yourself fortunate if the only problem is a blown fuse. This is a quick and easy fix.

Dirty or rusted battery terminals

Corrosion and filth on the battery terminals may also pose problems. You’ll notice that, over time, a green, dust-like substance will appear on the battery terminals. This is due to chemical reactions, as the battery terminals are made of lead. The solution is to remove the battery terminals, and then clean them with sandpaper. The goal is to create a clean connection between the battery terminals and poles.
