The Chrysler 300 alternator is primarily designed to provide current to the different electrical systems of the vehicle. It also recharges the battery to keep it at a specific voltage and replaces electricity that has been lost while the vehicle is in operation. The function of the alternator is so vital that it is a must to pay attention to it especially when it is starting to show signs of failure. Here are common indicators that your Chrysler 300 alternator is malfunctioning and what you can do about them:
It's a bit hard to determine where a certain noise is coming from. A bad alternator usually produces a loud, grinding sound, which could result from a failing rotor within the alternator. There are also parts inside the alternator, which spin in order to generate electricity. These components may also become worn out or damaged, resulting into a rattling noise. A burning smell may also be present, and it could be due to frozen bearings.
Listen closely for unusual sounds while the alternator is operating and confirm the problem by doing a visual inspection. If you find any physical damage on the alternator bearings, replacing the alternator would be necessary.
You may find your vehicle difficult to start, or it may stall or run roughly. This problem has many possible causes, and it would sometimes be difficult to tell if it is due to a bad alternator or a defective battery. Good thing, there are a couple of quick and easy methods that you can use to verify the cause of this problem-the headlight test and the battery test.
The headlight test is done by observing the headlights for changes in brightness. If the headlights flicker or dim upon pressing on the accelerator, you have a faulty alternator. On the other hand, the battery test is performed while the negative cable is disconnected from the battery and the engine is running. The vehicle would stall or completely stop when the alternator is defective, and this usually results from an inadequate supply of electricity. However, if the car continues to run, the battery is the problem and not the alternator.
