4 Common Auto Electrical Problems

Whether or not you drive an electric vehicle, electricity plays a major role in its operation. Many parts and accessories in your car or truck, such as the starter, lights, power locks and even your in-dash infotainment system, all rely on electricity to perform their duties. So when an electrical issue is suspected, where would an automotive mechanic begin their search for a cure? Oftentimes, one of the following four auto electrical problems will be at fault for your vehicle's troubles, so diagnostics will probably start here.

Blown Fuse

One of the most common auto electric issues in a car 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. A fuse is a small device used to protect electrical 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 juice.

Bad Alternator

The alternator is what keeps the battery charged and is responsible for generating the electricity that operates lights and other electronic systems, parts and accessories while the vehicle's engine is on. The alternator is connected to a belt driven by the engine's motion, which allows it to generate electricity. If you begin to experience dim or flickering headlights or notice other strange electrical occurrences, 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 Car Battery

If you experience complete electrical failure in your vehicle, meaning you're unable to start it, lights don't come on and so forth, you're likely suffering from a dead car battery. Batteries do 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.
