Simply put, a stator works together with a rectifier regulator to accomplish the same outcome as an alternator—to generate the DC power required to operate the motorcycle, ATV, side-by-side, etc. The stator is the coil of wire housed inside the engine case.
Will a motorcycle run with a bad stator?
If the stator is bad, the bike won’t run at all. The stator generates energy for spark. Assuming the air cleaner is clean and other general maintenance has been performed, if the bike won’t kick start but runs as you state, the problem is probably either the spark plug and/or fuel delivery.
How do I know if my stator is 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 makes a stator go bad on motorcycle?
A stator’s biggest enemy is heat buildup in the wire windings. … High engine temperatures can lead to stator coil open and closed failures, especially in modern motorcycle engines that submerge the stator in an engine oil bath to help dissipate heat.
Does a motorcycle stator charge the battery?
So, does a motorcycle battery charge while riding? The mechanism of a motorcycle does charge it’s own battery while the motorcycle is running. There is a device inside a motorcycle engine, usually referred to as a stator, that charges the motorcycle battery while the motorcycle is on.
How many volts should a motorcycle stator put out?
It should read anything above 12.0v but under 13.2v but ideally between 12.5 – 12.9 DC volts is required. Any less than this, you may start to encounter starting problems as the Battery will not have enough juice to turn the big twin motor over.
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.
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.
Will a bad stator drain a battery?
If the stator doesn’t provide enough power, the battery will begin to drain. … Readings over 1.5 Ohms are an indication that the stator is faulty. Next, check to make sure nothing is going to ground by connecting the red lead to the connector and the black lead to the negative terminal of the battery.
Can a bad stator damage a battery?
As far as the battery, yes a bad stator/regulator can destroy a new battery. If it’s run at a very low voltage without being recharged then it can be destroyed. It actually happens all the time. In most cases if we replace a stator or regulator the battery has to be changed as well as it won’t hold a charge.
What causes a stator to get hot?
Any Heat in a wire or a connector is a sign of excess current flow or too much resistance due to faulty or deteriorated connectors. I doubt that your stator has a leg shorted to ground as it puts out enough current on each to “Weld”.
Can a bad rectifier kill a stator?
Can a bad stator kill the Regulator/Rectifier? —-Yes. That is “yes” from an absolute standpoint. Normally no and less likely with the “Y” wound stator used in the DRZ, but yes it is possible.
What are the symptoms of a bad voltage regulator on a motorcycle?
Bad Voltage Regulator Symptom #2: Your Lights Are Dim
After all, the voltage regulator is supposed to keep the power flowing to the lights, so it’s no surprise that those lights don’t work right anymore once this part goes bad. This issue can extend to your headlights, dashboard lights and even your sound system.
Does a stator charge a 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.
How long do you have to ride a motorcycle to charge the battery?
Riding for only twenty minutes isn’t enough to get it charged either. Put the bike on a charger overnight, and then use a battery tender when you’re not riding to keep it charged.
Will a motorcycle stay running with a dead battery?
The answer is yes you can keep the motorcycle running if you remove the battery after you get it started. … The battery is what is used to get the vehicle started and the alternator (or the stator for the motorcycle) is what keeps the vehicle running.
