Stator Coil

The stator coils are the fixed copper coils in your alternator, and they work hand in hand with the rotor. When the rotor spins, it creates an electric current in the stator coils—that’s what powers the whole system. They charge the battery, and at the same time supply power to the ignition system and all the other electrical parts on your machine. These coils are usually made of copper wire. If the stator coils get damaged, the alternator will put out less power, and your vehicle’s electrical system will start acting up. FridayParts has high-quality, direct-fit replacement stator coils that will get your vehicle’s electrical performance back to steady, reliable shape in no time.

Diagnosing a Failed Stator Coil

A stator coil failure can manifest in several ways, depending on whether it powers your ignition system, charging system, or both. If you're experiencing any of the following symptoms, it's a strong indication that your stator coil needs to be tested and likely replaced:

  • No Spark or Weak Spark: This is the most definitive symptom on many ATVs, dirt bikes, and PWC where the stator directly powers the CDI or ECU for ignition.
  • Poor Battery Charging: If your battery constantly dies even with the engine running, the charging windings on your stator have likely failed.
  • Engine Stalling or Cutting Out: A stator that is failing can work when cold but cut out as the engine warms up and heat causes the windings to short.
  • Dim or Flickering Lights: Insufficient power from the stator will cause headlights and other electronics to perform poorly.

Our stators use top-quality copper coils and premium insulation materials—so they’re built to last, and perform just as well as (or even better than) the original parts. Check out our full range of stator coils now, and find the exact replacement you need in no time.
