Safety is important whenever working with electrical systems, so check your ownerвЂ™s manual for general tips. If this occurs, there are a number of potential causes to check out when troubleshooting. The warning light for the battery will stay on if a fault is detected in the charging system. This is a system test that indicates the battery light on the dash, along with any monitored components of the charging system, are working as expected. Top Reasons a Battery Light Comes OnД®very time the vehicle starts up, the battery warning light should briefly turn on, then back off after a few seconds. Various wires around the engine bay called ground straps connect parts of the wiring harness to the chassis, which help complete different circuits. The current (made of electrons) flows from one post of the battery, through the accessories, then into the other battery post. It is often a component of the engine control unit (ECU). The voltage regulator maintains the desired voltage while charging the battery. Note: Older vehicles may use a dynamo (also called a DC generator) instead of an alternator. This energy is then used to power things such as headlights, power windows, heated seats, radio, air conditioner, DVD players, and cell phone chargers. The alternator takes kinetic energy from the rotating pulley and converts some of this energy into AC power, which is then converted into DC current and stored in the battery. Recharging happens when the crankshaft pulley turns the alternator belt (also known as serpentine belt or accessory belt) which spins a rotor inside the alternator (which is sometimes referred to as a generator).

Chemical energy stored in the battery is how the vehicle can be started initially and then as it runs, the battery is recharged.
