6 Signs of a Bad AlternatorAlternator operation depends on a phenomenon called electromagnetic induction. When the engine is running, the drive belt turns a pulley on the alternator. That pulley causes the rotor inside the alternator to spin, which, in turn, creates a magnetic field that induces an electrical current in the alternator’s stator windings. Bad Alternator vs. Bad BatteryFirst, we need to know the difference between the alternator and the battery. The alternator is an engine-driven device that converts mechanical energy into electrical energy. When the engine is running, the alternator charges the battery, while also powering your car’s electrical system.
