How do I know if my stator or rectifier is bad?
Key Signs to Look For 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.
What can cause a stator to go bad?
To answer why stators fail, it is because the coating on the windings breaks down, usually because of heat, causing a short which can also burn the fine wire of the winding in two at the short causing an open circuit. The way to prevent failures is to prevent the heat.01-Dec-2011
Will a bad stator drain a battery?
When a stator has gone bad, that means the motorcycle is running off of battery power alone which will quickly drain it. ... Batteries aren't able to store AC current so the regulator/rectifier converts power into a type of current the battery can store.
Can you repair a stator?
Fixing a stator usually involves unwinding and cleaning the original stator core, then rewinding it with a machine or carefully by hand. It starts with looking at the coil heads for damaged or burned wires, then cutting out the protective rubber coating from damaged coils.27-Mar-2021
Will a motorcycle run with a bad stator?
Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark. As a result, if your stator is going bad your motorcycle will run very poorly.
Will ATV start with bad stator?
Will an ATV 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.
Does a stator charge a battery?
An ATV uses what is called a stator system or magneto system to charge its battery. ... Any time the engine is running, the stator is continuously generating an electric charge. Some of the electricity is used to power the bikes different electrical components.
Will a motorcycle start with a bad rectifier?
A rectifier converts alternating current (AC) to direct current (DC) to charge the battery. ... Since motorcycles require battery power to start them up, a bad rectifier will eventually result in the motorcycle not able to start.
How long can a motorcycle sit before the battery dies?
The average motorcycle battery will die after 2 – 4 months without running. Newer batteries can last longer with an average of 3 – 5 months until dying whereas older batteries will not last as long giving it an average of 1 – 3 months until the battery dies while the motorcycle is sitting.
How much does it cost to fix a stator?

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.
What happens if your ATV stator goes 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. In this article, you’ll find everything you need to know about your ATV’s stator, ...
How much does it cost to replace a stator on an ATV?
Stators aren’t usually expensive for most ATVs. They will usually cost under $100 for the part and can be significantly less.
Can you clean a stator if it is bad?
You may need to clean the connectors. This is a free and easy fix so try it out if your battery is still good. Voltage regulator rectifier unit: If your voltage regulator is bad, you’ll have the same problems as if your stator is bad. This can make it difficult to determine, which is the problem.
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, ...
What are the different types of stators?
There are three different types of stators: Single Phase Stators: Not as powerful. Uses a single wire to create the coils that circle the iron core. You will see two wires in the cable coming off the stator. Three Phase Stators: Most ATVs use a three-phase stator because they are capable of producing more electricity.
What is the purpose of a stator?
The stator’s primary job is to recharge your ATV’s battery while it is in use, but many ATVs have stators capable of doing more. Your stator might include one or more of the following: Crank position sensor: This is a small boxy component that should be attached to the stator at the cable.
Why is a stator important?
The stator also performs the extremely important role of generating the power for the spark plugs in the engine. Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark. As a result, if your stator is going bad your motorcycle will run very poorly.
How to tell if your stator is bad?
The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfir ing). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced. In this article we will dig into these symptoms and what causes them.
Can a stator stop a motorcycle from starting?
As a result, if your stator is going bad your motorcycle will run very poorly. Eventually, your stator can prevent your motorcycle from starting at all . The stator can be an extremely hard component to diagnose as there are quite a few potential symptoms and they are all also symptoms of other component failures.
Why is my motorcycle running so poorly?
Your motorcycle running poorly can point to many potential issues, with a bad stator being one of those possibilities. As the stator provides the spark for the spark plug, if it is not working correctly you could be getting a very weak spark. This could be constant or completely irregular and sporadic.
Why is my motorcycle so hard to start?
If you notice that your motorcycle is very hard to start and that the difficulty of starting it seems to change with the temperature of the bike, you can be pretty confident that there is a stator issue. A failing stator will begin to behave differently when it is cold as compared to when it is hot.
How much does it cost to repair a stator?
Stators can be very expensive to replace entirely. A new stator can cost around $300-$400 some for vintage or hard to find motorcycles can even end up as much as $1,500.
Can you start a motorcycle with no spark?
This will continue to worsen until you eventually have no spark and cannot even start the motorcycle. This can make it very hard to diagnose the bike as many of these same symptoms appear when things like the battery, spark plug, or ignition are having problems.
Why does a stator go bad?
They get old, they get hot, they break down, and they just flat out go bad! If the windings get corroded by a dirty engine, they can fry themselves. Or short out. So a dirty engine can cause a stator to go bad. As well as running too hot.
What happens if one winding fails?
Meaning, that one winding will produce the electricity that is used for one, two, or three different cylinders! So, if one winding will fail. The engine will lose spark on one or all of those cylinders. Making the engine run very poorly. This is why you can have a bad stator, but the engine will still run, just very poorly.
Can an outboard run with a bad stator?
Yes, certain outboards will run with a bad stator, but not very well. No, other smaller outboards will not run with a bad stator. The stator produces the electricity that the engine uses to operate the ignition system to run the engine. There are many different factors and variables to this question! Here are all of the things that you need ...
Why do you need a voltage adapter for a stator?
Because there is also a voltage reading that can be performed to see what kind of power the stator produces. But you will need to have a digital voltage adapter to test this to keep the fuses in your meter from blowing. So be sure to test your engine’s stator based on the service manual specs and tests!
What is a stator in an engine?
A stator is a component on an engine that is attached under the flywheel of the engine. The engine’s flywheel has magnets attached to the inside of it, that spin around the stator. The stator is made up of windings that produce alternating current electricity. As the magnets on the flywheel spin around the windings when the engine is running.
How many cylinders does an outboard have?
Smaller outboards that only have one, or two cylinders. It will not even start and run if the stator has failed! Whereas larger engines, that have 4, 6, or 8 cylinders. Will use a stator that has different parts to it. Some stators will be broken down into two, three, four, or even six halves!
What is the makeup of an engine?
This AC electricity is used by the engine to run all of the ignition components of the engine. That makeup is what creates the spark for the engine to run. For a more in-depth description of how an engine works.
