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.
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 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 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.
What are the symptoms of a bad stator on an outboard?
You can know you have a bad stator by looking at it. If the stator is covered in salt and corrosion. Or you see it has melted or burnt windings on it. Then you could almost bet that it is bad.
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.
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.
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.
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.
Does a stator charge the battery?
In simple terms, the battery provides this power. The battery would quickly be depleted, though, if not for the star of the charging system show, the stator. Think of your stator as the piece that makes electricity to keep your battery charged up to make all that electrical stuff on your bike work.
Can a stator be rebuilt?
All rebuilt stators require a core exchange and come with a one year replacement warranty. Most new and rebuilt stators are built to stock specification, but we do offer some high output stator versions as part of the Hot Shot Series so you can get even more electrical power from your machine.
What tests can be performed on a stator?
These additional tests include voltage withstand testing, insulation resistance, polarization index and dc winding resistance measurements, as well as inter turn fault detection. They assess not only the insulation integrity, but also help to identify connection problems and weak points in the stator winding.
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 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.
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.
How do you know if your outboard rectifier is bad?
To confirm this, you simply need to use the voltmeter to diagnose that the battery has too high of a charge while the engine is running and producing voltage. Back to those 13.5-14.3 VDC readings. This indicates that the rectifier has failed to convert excess power appropriately.
What is a trigger on an outboard motor?
Your outboard trigger tells the switchbox when to “fire”. The inner ring of your flywheel has magnets which pass close to the triggers coils. Each time the magnet passes, the trigger sends a low voltage “signal” to the switchbox.
Will outboard run without rectifier?
Banned. If it starts and runs without the rectifier, it’s running off the battery and will run only as long as the battery or batteries hold enough charge.
Can a bad voltage regulator cause no start?
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.
