If you’re a new driver, you may not know what happens when an alternator goes bad. You may be wondering if the car starter has gone bad or if the battery is starting to die. The fact that an alternator can fail may not even enter your mind. Don’t wait until you’re stranded in a dark parking lot, but have your mechanic check out your vehicle’s starting system to pinpoint the problem.

If the starter and battery are ruled out as the cause of your starting problems, that means the alternator is failing to do its job of keeping the battery charged. Because your battery isn’t receiving the power it needs, it will eventually be completely drained of power.

Do you know what happens when an alternator goes bad? Don’t wait to find out! Ask your mechanic to inspect your car’s alternator about every 12 to 24 months. This inspection should include:

  • Brushes, at specific mileage or time intervals.
  • Test the field of outputs.
  • Visual inspection (while your vehicle is in for other services) for damage from heat, vibration, and external contaminants to the connections.
  • Check for leaking fluid.
  • Check the tension of the belts about every 30,000 to 40,000 miles (too tight can damage the bearings and too loose prevents proper charging).

Tip to Remember: The alternator has to work harder in today’s vehicles than in older vehicles. In addition to the radio, lights, and ignition, the alternator now has to power GPS units, heated seats, power windows, seats, door locks, built-in computers, and sensors, plus more!
