Internal Combustion Vehicle Electrical Systems

Your car’s electronics do more than just power your windows or play your radio, they power critical safety and operations systems within your vehicle. If there’s an issue with one electrical component on your car, there could be issues with others as well.

The electrical system in your car is composed of three main components: the battery, the starter, and the alternator. The battery gives the starter a spark of power, which then turns on your engine. While you drive, the alternator keeps your battery charged so that the electronics in your vehicle can continue to work.

High-quality batteries, alternators, and starters are recommended to ensure your vehicle’s electronics are reliable. If you’re having trouble with your car’s electronics, take your car to a nearby Bosch Auto Service for inspection.

Car Electrical Issues?

The battery runs everything from the ignition to advanced driver assistance systems (ADAS) in your car. When these systems don’t work or your vehicle has aged or damaged wiring, your comfort and safety could be at risk.

Dashboard Lighting

Most modern vehicles are designed with a dashboard that relies on electronics to display warning lights and indicate important information about your car. If issues arise with your electronics, your vehicle’s dashboard indicators may fail. Here are a few warning signs to look for that indicate dashboard malfunction:

  • Dim lights for indicators
  • Lack of warning signs when problems are present in the car
  • Slow response to input changes (such as switching views on gas mileage)

Many factors can influence whether or not the dashboard is working properly: a low battery charge that doesn’t provide proper power to the system, a dirty sensor that can’t register potential hazards, or a bad fuse, to name a few. If you notice any of the signs above, it’s time to get your car’s electronics diagnosed and repaired.

How do I know if my car’s electrical system is bad?
There are many common signs that your car’s electrical system is failing. If your sensors stop working, your engine won’t turn on, or you smell something burning when operating your vehicle, you could have an electrical malfunction. If your car senses an issue with your electrics, it will also turn on the battery light on your dashboard. If you see a light turn on that looks like a battery with the letters ALT or GEN, it’s time for an electrical diagnosis.
Why isn’t my radio working?
The radio in your vehicle is an electrical component much like any other. Your radio could fail to work if there’s a blown fuse, faulty wire, or another broken component. If your battery is low on charge, it may also cause your radio not to work.
Is my car battery weak?
In many cases, a problem with your electronics could point to an issue with your battery. For most, charging the battery or repairing the cable connections can fix the issue. But if your battery is older or faulty, charging won’t fix the problem and you will need your Bosch Auto Service mechanic to fit your vehicle with a new battery.
