How Can You Tell if Your Alternator is Bad?

Perhaps the most common sign that the alternator in your vehicle needs attention is that the battery goes dead. However, a dead battery doesn't always mean you have a bad alternator. After five to eight years, the typical car battery simply reaches the end of its useful life and needs to be replaced. But before you replace a dead battery, it's a good idea to have it and the alternator tested.

If you're familiar with using a voltmeter and you can get the vehicle's engine to turn on, you can check the voltage at the battery. While it's a 12-volt battery, you'll want to see 13 or 14 volts at the battery when the engine is running. That tells you that the alternator is sending power to the battery. Even with this basic test, you're still better off leaving such diagnostic and repair services to the certified technicians who know your vehicle best.

Does a Bad Alternator Need to Be Replaced, or Can it Be Repaired?

To answer this question, it helps to have an idea of how the alternator works. We'll spare you the complicated physics behind the electromagnetic induction. Instead, know that the alternator generates electricity in part by rotating a magnetic core against brushes. Eventually, these brushes will wear down. Often, the alternator can be disassembled and the brushes, along with the bearing, can be replaced. This is most of what goes into rebuilding an alternator, and this service could have you back on the road after saving a few bucks. However, sometimes the wear is severe enough that it's more efficient and cost effective to simply replace the whole alternator. A certified technician will be able to advise you on the best option.
