When your car's alternator starts to fail, you're likely to notice some unsettling signs—perhaps your dashboard lights flicker, the battery warning illuminates, or your car's electrical systems begin to act erratically. It can be a stressful situation, especially considering how crucial the alternator is to your vehicle's function. Naturally, one of the first questions that arises is, "How much is this going to cost me?"
