The most important thing to know about your car’s electrical system is that it’s not working properly if you’re not using it. You probably start every trip by turning on the lights, powering up the stereo, and notching up the temperature, so you can understand why so many drivers overlook the electrical system. However, if any of these features fail to turn on, or if the headlights dim when you step on the gas, then the chances are good that your car’s electrical system is on the fritz.
Read on to learn more about the best electrical system tools.
