For decades, vehicle electrical systems have been responsible for starting your car, recharging the battery and providing power to components like lights and power windows. Nowadays, vehicle electrical systems handle more features like power seats, heated seats, navigation systems and entertainment centers. Even components like steering and braking are electronic.
Electrical issues can create expensive repair if they are not addressed quickly. If you are experiencing any of these symptoms, come to Sant Automotive in Webster Groves for a diagnosis.
Your car is highly reliant on complex electrical systems. Therefore, problems are commonly misdiagnosed, and it is important to request a thorough inspection. We start by performing an interview with our customer to let them describe the symptoms. Then, we will check any error codes with our diagnostic scanner. Troubleshooting common electrical problems would start with us popping the hood and inspecting your battery. We will also check the alternator and the charging output. Finally, we will take a look at your spark plugs, wires and other electrical components.
Causes of electrical failure could be a dying battery, a failing or overcharging alternator, wires coming loose, and more. These problems will definitely harm other systems in your vehicle if they are not addressed right away. Get your electrical system under control and stay on the road at Sant Automotive.
Basic electrical systems consist of a battery, alternator, ignition switch and voltage regulator. When you turn the key in the ignition, your battery gives current to the starter, which powers the alternator and charges the battery in return. Your car electrical system is a closed circuit with the battery as the independent power source. Current flows from the battery along a cable to your other systems, and then back to your battery.

Your car runs on a direct current system (DC), as opposed to your home with runs on alternating current (AC). Direct current is a single wire system. In the most basic terms, your car electricity flows from the positive battery terminal, through your cars electrical components and back to your battery through the negative terminal (ground) in a single direction.
