4 Common Auto Electrical Problems


4 Common Auto Electrical ProblemsWhether or not you drive an electric vehicle, electricity plays a major role in your car's operation. Many accessories in your car or truck, such as the radio, lights, power locks and windows and even your in-dash infotainment system, all work electronically. So when an electrical issue is suspected, where would an automotive mechanic begin their search for a cure? Most likely one of the following four auto electrical problems are going to be at fault for your vehicle's troubles, so diagnostics will probably start here.

Blown Fuse

One of the most common issues for electrical systems is a blown fuse. If a specific system stops working, such as the radio or the turn signals, you will want to check the fuse box. An electric fuse is a small device used to protect electric circuits in your vehicle against high current caused by short circuiting (see below) or overloading. Most electrical systems in the vehicle are routed through a fuse to ensure they don't receive too much electricity.

Bad Alternator

The alternator is what keeps the battery charged and is responsible for generating the electricity that operates lights and other electronic systems and accessories while the vehicle's engine is on. The alternator is connected to a belt system under the hood, which allows it to generate electricity from the motion of the motor. If you begin to experience dim or flickering headlights or notice other electrical problems there is a good chance it is time for a new alternator.

Short Circuit

A short circuit happens when an electrical circuit allows electrical current to travel along an unintended pathway, often where essentially no, or low, electrical impedance is encountered. This may happen if the coating on wires wears away and the wiring comes into contact with metal on the vehicle unintentionally. A short is often the cause of a blown fuse.

Dead Battery

If you experience complete electrical failure in your vehicle, meaning you're unable to start it, you're likely suffering from a dead battery. A completely dead battery will mean not only will your car not start, but your lights or radio or other electrical items won't be able to work either. Batteries wear out over time and need to be replaced, but they can also go dead due to an accessory or lights being left on while the vehicle is not running for an extended period. If the latter happens the problem can usually be resolved with a jump start.
