Top Signs of Alternator Problems

  1. A dash light coming on for a brief moment, maybe dimmed headlights and a few flickering gauges. Perhaps there's even an odd smell, or a growling sound coming from under the hood.
  2. Within the instrument cluster of most cars built in the last decade is a warning light dedicated to signaling an alternator issue. In most cases the light is shaped like a battery, though some show "ALT" or "GEN," meaning alternator or generator, respectively. 
  3. Atlernator
  4. Since the alternator supplies the vehicle's electrical needs, when it begins to lose its potential so do the accessories that draw on that electricity. Drivers may begin to experience erratic symptoms ranging from dimming or extremely bright headlights and dash lights, to speedometers and tachometers that simply stop working for no reason. Other accessories, like heated seats or power windows may experience a slowdown as well.
  5. While not technically an alternator problem, a car that won't start is a definitive notice from your car that there's a problem in the starting system. When the key is turned, you'll hear a tell-tale clicking of relays ticking over but nothing else happens. After a time, even that noise stops. The immediate problem is usually a dead battery; but the question a driver should ask is, "Why is it dead?"
  6. In this case, everything with your car's alternator seems to check out OK -- no belt issues or other visible signs of trouble -- but the car's battery is dead, as is most of the car's electrical equipment. What's happening is the alternator is producing electricity, but it's either not going anywhere or it's not the right type.
