What happens when a stator goes bad?
The stator coil generates the power for the spark plug and other accessories on small engines Without a stator there would be no spark at all, meaning the engine won’t run. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up.
What causes motorcycle stator failure?
The two most common causes of Stator failures in our design will be through not changing the oil+filter and coolant at the correct service points. Old oil slowly becomes acidic and abrasive and also causing the engine to rum warmer than needed this causing premature engine component wear.
What does Rectifier do on motorcycle?
The rectifier regulator converts AC power to DC allowing the alternator to charge the battery, and controls the amount of power delivered to the battery. Without a functioning rectifier-regulator, a weak, dead, or overcharged battery would be the result.

First perform the static stator tests. With the ignition switch in the “Off” position, disconnect the regulator from the stator. Set the multimeter to “Resistance” or “Ohms” on the lowest scale, and insert one probe into one of the stator pin sockets. Touch the other probe to any chassis ground.
What is a stator on an ATV?
Stators can look quite different depending on the brand of ATV and model, but in general, they consist of an iron core, wire coils, and a cable that allows the stator to be connected to the voltage regulator. Magnets spin past the coils, which creates an electric current in the wires, which is then passed along to the voltage regulator, ...

Why do ATVs use three phase stators?
Three Phase Stators: Most ATVs use a three-phase stator because they are capable of producing more electricity. It uses three wires to create the coils that circle the iron core. The cable coming off the stator will clearly have three wires (usually yellow, but not always) if you have a three-phase stator.

Where is the Stator Located on a Four Wheeler?
The stator is located on the inside of the engine of your quad. While the position of your engine can vary a bit based on your model, this part is often times located under the seat, behind the engine cover. If you have the service manual of your ATV, then you will find detailed information both about the location of your engine and stator.
Symptoms of Bad Stators on ATV
The main symptom of bad stators on ATVs is that the battery does not charge during your ride. If your battery charges perfectly well with a separate charger but not during usage, then the problem most probably comes from the stator. The voltage regulator can be at fault in this case too, but this is why we test our parts before making a purchase.
