Common Signs of Auto Electrical Problems

With cars becoming more tech-driven nowadays, we’ve become more reliant on the electrical system more than ever. There are three main components in the electrical system: the battery, alternator, and starter. The moment any of these begin to fail, you’ll notice a significant loss in your vehicle’s capabilities.


Finding and diagnosing electrical system problems is not an easy task, and it requires skills and expertise. Additionally, you might need a scan tool, which some people don’t have. Below are a few of the common signs that mean it’s time to take your car to Future Auto Service:

Hard or Slow Cranking Engine

Automobiles take in a significant amount of energy upon startup, and it grabs power from the car battery and starter to do so. If the battery can’t supply enough power, your engine will fail to spark the fuel and air mixture. The clicking or cranking noise often occurs when you try to turn your key or push the start up button.

Blown Fuse

Most vehicles have a fuse box to prevent short circuits and overvoltage. Blown fuses are more common than you think, and they will need to be replaced. If this happens all the time, there may be a deeper issue at play.

Battery Issues

Car batteries can last up to 5 years if properly taken care of. They should be positioned properly and free of corrosion. You can care for your battery by having it regularly tested and inspected.   The cables and connection points should be clean and tucked away.

Dim or Blinking Lights

Dim lights can be attributed to a bad battery, or more commonly, a faulty alternator. The two issues can give off the same symptom, which is why it is important for a professional to check. Otherwise, the bulbs could be going out.

Electrical Accessories Failure

Features like the GPS and infotainment system, power seating, power windows, windshield wipers, and more contribute to the comfort and convenience of driving. These draw a lot of power, and most of it comes from the alternator.
