What problems can a bad stator cause?
The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.
How do I know if my 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.
Can 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.
How do I know if my stator or rectifier is bad?
Key Signs to Look For 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.
Will a bad rectifier damage a stator?
If the rectifier/regulator failure results in too low resistance the stator probably will burn (too much current). If I disconnect the rectifier/regulator the voltage will go up, but how high? Is it possible that the voltage will go high enough to destroy the isolation?Mar 13, 2010.
Will ATV start with bad stator?
The stator of an ATV works to recharge your battery while your vehicle is running, similar in function to a car’s alternator. When the stator goes bad, your ATV will only run until the battery goes dead, which is not very long.
What happens when the regulator rectifier goes bad?
Depending on the location of the regulator rectifier, the part can easily overheat. Ground connections are important for good voltage, and if there is faulty voltage, the regulator rectifier can run hot. Bad grounding, corroded battery connection and poor or loose battery connections will cause faulty voltage.
Is stator same as alternator?
Stators are inside the engine case. An automotive style alternator is a fully self-contained, externally mounted unit that creates DC current. Another difference between stators and automotive style alternators is the type of magnet uses. Stators use a permanent magnet, and automotive alternators use an electro-magnet.
What are the symptoms of a voltage regulator going bad?
Bad Voltage Regulator Symptoms Too High Voltage in the Battery. There are two ways a voltage regulator can fail. Dead Battery. Battery Light or Check Engine Light. Inconsistent Operation of Electrical Components. Vehicle Dies While Running. Dimming/Pulsing Lights.
How many volts should my stator put out?
For each 1000-rpm, a 32-amp stator should have 18 volts AC (VAC) per it. It should be 36 VAC by 2000. 54 VAC is what it should be at 3000 RPM.
Can a bad stator cause bogging?
yes, A stator thats breaking down will work good when cold but fail are act up as soon as it warms up, The symptoms you mentioned sound like it could be a stator. Ive seen A few ZX sleds with this problem.
What causes stator failure?
When a stator fails, it is largely due to the degradation or aging of its insulation through external occurrences and materials being introduced into its system.
What makes a stator go bad on motorcycle?
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.
Why does a stator burn out?
The AC current heats up the stator and the heat destroys the insulation and ultimately carbonizes it turning it into a low resistance brick.
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.
Can a bad battery damage the rectifier?
over time.a badly suifated battery overworking the voltage regulator AND the stator, associated wiring and connectors. IMHO absolutely within reality that further damage to those other components could occur due to resistance and resultant heat.
Can a stator overcharge?
It’s impossible for a stator output more voltage then it was designed to do. It would have to magically create more windings. A bad stator can in fact still charge but not very well so the actual answer to your question is that a stator is only capable of outputting less charge if it’s failing.
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.
Does a stator charge a battery?
An ATV uses what is called a stator system or magneto system to charge its battery. This is a fairly simple and robust system located on the inside of the ATV’s engine. Any time the engine is running, the stator is continuously generating an electric charge.
How do I know if my CDI box is bad?
Symptoms could include misfiring, dead cylinders, backfiring, bizarre tach behavior, and countless other things related to how your engine’s running. The problem may get worse as the bike warms up. It might not even hold low revs at all.
