Alternators

The principal parts of the charging system are the battery, the alternator, and the voltage regulator. A truck alternator plays a significant role in the functioning of any gasoline-powered vehicle. The alternator transforms mechanical energy into electrical energy with the help of induction. It also charges the battery to replace the energy used to start the engine. The voltage regulator prevents the overcharging. While your charging system is pretty complex, it is easy to understand. When you turn the key or press the ignition button, the battery sends voltage through the spark plug wires to the spark plugs. This spark ignites fuel vapor and starts the engine. However, electricity is needed to keep the engine running. Your Mopar alternator supplies energy once the engine is running. It also provides the electricity to operate all the lights on your car and every other electrical accessory. Over time, even OEM alternators will wear out. When this happens, you'll need to replace it with a genuine Mopar alternator to ensure that you get the perfect fit as well as the right match for your wiring harness and enough electricity to safely operate all of your systems.
