Without your car’s electrical system, you wouldn’t be able to start the engine, turn on the headlights, or even control the windows and mirrors. There’s no denying that it’s crucial for a functioning car. Look out for these signs that your vehicle needs an auto electrical repair.

What Car Electrical Issues Should You Watch Out For?

1. Dead or Dying Battery 

If the battery’s dead, the car won't start. If it’s dying, you might notice symptoms like dimming lights or the radio not turning on. Because your car’s battery depends on chemical reactions, temperature affects its performance. The heat will speed up these chemical reactions and cause corrosion, whereas cold weather will slow down your battery and may even freeze it. Alternatively, the battery might die if you leave headlights or dome lights on overnight. The average car battery lasts around four years, so if yours is past that age, it might be at the end of its lifespan. 

2. Faulty Alternator 

Your car’s alternator keeps the battery charged. With the turning motion of the engine, the system of belts connected to the alternator spin and generate electrical power. Symptoms of a faulty or failing alternator include dim lights, grinding or squealing noises, or a stalling engine. An alternator issue can also cause a dead battery.

An alternator lasts around seven years, so if it’s been longer than that, you should visit your auto electrical repair shop. Alternator issues might also result from corroded or damaged wires or a broken belt. Belts, in particular, are flimsy and will break with enough wear and tear. 

3. Defective Spark Plugs 

The car’s spark plug creates a small explosion in the engine’s cylinder head, thus powering its pistons. The spark plug consists of an insulated electrode, insulated wire, and an ignition coil; these components will wear and cause issues over time.

When plugs or wires become corroded, the spark plug will not receive an electrical charge and help the engine operate. Depending on the type of spark plug you have, it can last anywhere from 10,000 to 100,000 miles. Symptoms of defective spark plugs include poor fuel economy, slow acceleration, and trouble starting the vehicle.
