Many malfunctions that occur in cars may be diagnosed as electrical problems. The cause is usually related to the electricity that is being generated by the battery or alternator. Troubleshooting can be a frustrating task, especially if you’re not knowledgeable enough.
A crucial consideration when working on automotive electrical systems is ‘safety’. Although the risk of being shocked is low, the danger is accidentally shorting out a hot circuit. This may lead to damaging the wiring, PCM or other onboard electronics – and fire.
Electrical Problem Signs
For your safety, and your car’s, it is best to let professional auto technicians handle the electrical troubleshooting. How do you know when it’s time to bring your sports car to a Maserati or Porsche workshop? Here are some of the signs you have to look out for.
Vehicle won’t start. It’s the most common electrical problem you will probably experience. If the interior lights aren’t working and the car won’t start, the problem is likely a dead battery. If you hear a clicking sound, it might be the starter. Go to an auto repair shop for final diagnosis.
Lights dim while driving. Does your dashboard or headlights dim when you’re driving at low speeds? There might be a problem with your car’s alternator, or voltage regulator. It could also mean that the battery is on its last legs, or have trouble holding a charge.
Visible battery damage. Even if you don’t know troubleshooting, you can still inspect the battery from time to time. Are there corrosion stains or buildup around the terminal? It may be a sign that the battery is leaking, experiencing a problem, or nearing the end of its life.
Brake lights don’t work. You tried having your break lights replaced, but it’s still not working. The problem may not be with the bulbs. It might be the fuse. It can also happen to some specific part of the vehicle. Let an auto shop check if you don’t need to replace a fuse.
Electrical System Service
If you’re an Aston Martin owner, the more you have to bring your car to a service center specializing in luxury vehicles. Batteries usually last between three and seven years, so it will be a smart decision to have it checked once you experience any of the signs.
Remember, the contents of the battery are corrosive, and they will damage bare skin. That’s why it should not be just a DIY task. There are dozens of components needed to route power in your vehicle’s electrical system. It can vary greatly according to vehicle make, model and age.
