Regulator changes ac volts from the stator to dc volts for the battery and other electronics. If you have a no spark condition,first check the resistance on the pick up coil white and white/red wires leading to the cdi.
What is a voltage regulator rectifier? The regulator acts as a filter between the stator and the battery to ensure the battery receives the proper voltage by sending any extra to the ground. The rectifier part of the voltage regulator rectifier converts the stator’s alternating current (AC) into direct current (DC) that can charge the battery.
What is an ATV stator? 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.
How does an ATV charge its battery? An ATV uses what is called a stator system or magneto system to charge it’s battery. This is a fairly simple and robust system that’s located on the inside of the ATV’s engine. 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.
Do motorcycles have ac voltage? AC voltage is generated in the alternator’s stator coil. For the most part, motorcycles are on a three-phase system for efficiency purposes, where three wires connect the stator and regulator rectifier. Even so, there are some single-phase systems available as these are cheaper to manufacture,

Can a bad rectifier kill a battery?
In general, there are two primary ways that the regulator rectifier can fail. 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. around 13 volts, the bike will start to drain the battery.
Will a motorcycle start 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 problems can a bad stator cause?
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 happens if voltage regulator fails?
A damaged or failed voltage regulator can rapidly diminish the alternator’s ability to cycle power from the battery. Dead Battery. A burned-out voltage regulator will diminish the vehicle battery’s ability to charge or stop it altogether. Unpredictable Engine Performance.
What happens when the regulator rectifier goes bad?
In general, there are two primary ways that the regulator rectifier can fail. 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. around 13 volts, the bike will start to drain the battery.
How does a voltage regulator go bad?
They usually fail because they’re under rated for the constant current draw. Running the motor with the battery disconnected – or even a poor contact on the battery terminals – can also blow them. This is because the ignition circuits produce spikes of around 400V, which the battery sinks.
Can you bench test a voltage regulator?
Why does a stator burn out?
Heavy current load, short circuits. A loose wire handling current can damage everything in the system. This voltage can be thousands of volts from just a 12 volt circuit. That high voltage spike can punch through the enamel insulation in the stator coils and cause them to short out.
Can you drive with a bad voltage regulator?
A bad voltage regulator may cause it to simply not work or behave erratically. You’re not likely to be able to start the car at all, but even if you could, it wouldn’t be wise to do so without knowing how fast you’re driving, how much fuel you have left, and other critical info.
Can a bad rectifier cause no start?
Yes, a faulty rectifier can cause no-spark condition. In both kinds of engines, the battery will die eventually because the lack of a rectifier will mean that the alternator is not charging the it. Eventually the engine will not start.
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 you test a voltage regulator?
We take the probes of the multimeter and place the positive probe (normally the red probe) on the input pin of the voltage regulator and the negative probe (normally black probe) on the ground pin. The voltage that we should read should be higher than the voltage the regulator is rated to output.
How do I know if my regulator rectifier is 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.
Can a bad rectifier damage a stator?
If the rectifier/regulator failure results in too low resistance the stator probably will burn (too much current).
What causes a stator to fail?
There are a few things that may cause a stator to fail. Too heavy of a load when operating accessories (winch,heated grips,headlights, etc). If working several of these items at one time (plowing/pulling/possibly stuck at night) you would overload the system. This could cause either the stator or rectifier to fry.
How do you test a ATV voltage regulator?
What causes a motorcycle stator to burn out?
Heavy current load, short circuits. A loose wire handling current can damage everything in the system. This voltage can be thousands of volts from just a 12 volt circuit. That high voltage spike can punch through the enamel insulation in the stator coils and cause them to short out.
How do you know when a stator is bad?
Insert each probe into a stator socket. You should read around 0.2 to 0.5 ohms. If you show an open circuit with the “Open” or infinity reading or have higher resistance, then the stator is bad and you must replace it. If these tests all produce positive results, then the stator itself is good.
How do I know if my ATV voltage regulator is bad?
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. When this happens, it’s only a matter of time before the engine stops completely.
What does a voltage regulator do on a quad?
Regulator changes ac volts from the stator to dc volts for the battery and other electronics.
