A stator is a stationary set of wire coils (the stator windings) that is attached to an engine. In simple terms, the stator generates the electricity that powers the battery in a motorcycle, ATV or side-by-side, and is therefore responsible for powering the vehicle itself.
monsterscooterparts.comImage: monsterscooterparts.comAlong with the flywheel, an ATV stator is a key component of the vehicle’s electrical system. A modern ATV stator is usually a “generator stator” meaning that its only purpose is to charge the battery.
What is the function of the ATV stator? An ATV stator has two primary functions; to charge the battery while simultaneously charging the CDI unit through the use of a special coil mounted on the ATV stator. This coil in turn sends that power to fire the engine.
What is a motorcycle stator? Installed in smaller motor driven vehicles, such as motorcycles, snowmobiles, jet skis and ATVs, stators produce an electrical charge to power accessories, fire spark plugs and recharge batteries. Functioning similarly to the alternator or generator in an automobile, stators are coils of wrapped wire producing DC
What does a stator do? Installed in smaller motor driven vehicles, such as motorcycles, snowmobiles, jet skis and ATVs, stators produce an electrical charge to power accessories, fire spark plugs and recharge batteries.
What is a static stator test? When you have a problem with the electrical system in which the engine on your motorcycle, ATV or UTV won’t run, you’ll have to do a static test. The static stator test involves measuring from coil to coil — or phase to phase — within the stator, and also measuring from each coil/phase to ground.

Can you run a quad with a bad stator?
If your stator is bad, the battery of your ATV will not charge while the ATV is running.
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.
How do I know if my ATV stator is bad?
If your stator is bad, the battery of your ATV will not charge while the ATV is running. This can be caused by several other problems, however, so the only way to be sure that your stator has gone bad is to perform a series of tests using a multimeter.
Will a motorcycle run with a bad stator?
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.
How do you test a stator with a multimeter?
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.
How do I know if my motorcycle Rectifier is working?
To check the regulator, connect the meter leads to the bike’s battery as it’s running. The reading should not be higher than 14.5 volts or lower than 13.5 volts. If the reading is higher, this means the battery is overcharged and you may need to replace the regulator rectifier.
How do you test an ATV stator?
– Pull both of the stator’s pin-connector plugs from the wiring harness with your hands; the two plugs each have one male pin and multiple female sockets.
– Set a multimeter to the DC “ohm” or “1X” or setting.
How do you test a quad stator?
– Pull both of the stator’s pin-connector plugs from the wiring harness with your hands; the two plugs each have one male pin and multiple female sockets.
– Set a multimeter to the DC “ohm” or “1X” or setting.
Can a bad stator damage a rectifier?
Registered. To answer your question yes it can, there are three diodes(phases) within the rectifier that allow current to go in one direction through the device (ie. Stator > Rectifier > Battery). But will not allow currrent to flow in the opposite direction.11 Sept 2008
Will a motorcycle run with a bad Rectifier?
The rectifier is part of the charging system. If you put a freshly charged battery in your motorcycle, and you have a bad rectifier, it won’t stop your motorcycle from starting, but your battery wouldn’t stay charged. The regulator/rectifier on your motorcycle performs two functions.
What causes stator failure?
The primary root cause of electrical tracking failures is the presence of any contamination build-up on the stator winding insulation. motor operation. Specifically with stators, extreme vibration will cause friction between the coils and the stator core.
What can cause a motorcycle stator to go bad?
It’s usually the insulation between windings breaking down or more often windings to metal – SOME of that (age related) is chemical and heat, but often it’s a mechanical failure – the windings are either loose and wear the insulation away between turns, or more common the insulation on the inside wears away against the
What goes bad on a stator?
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 a motorcycle stator to fail?
Vibration and heat are the two biggest contributors of a failing stator. Electrical anomalies contribute too. I’d say for a 23 year old bike, that’s not too bad.
What happens when a rectifier goes bad?
First, the diode can burnout and cause the battery to drain. You won’t have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. You’ll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery.
What are the symptoms of a bad stator?
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.
Will ATV start with bad stator?

What causes a rectifier to fail?
Other common causes for regulator rectifier failure involve the battery. If the link is bad and the voltage is faulty, this can cause the regulator rectifier to run hotter than usual. Things like poor grounding, a loose or weak battery, and a worn battery connection can all lead to regulator rectifier failure.
