Your alternator is an integral part of your starting and charging system, helping to restore power to the battery that is lost while starting and running the engine. A failing alternator will lead to dimmed lights, a weak or dead battery, difficulty starting, strange smells, and odd sounds such as grinding or whining. It can also affect other parts of the charging and starting system causing further failures. Of course, other components of the systems could also be the culprit, which is why you need to bring it to Falcon Auto Repair for inspection and testing.
