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.
What can damage motorcycle stator?
The other main cause for your stator failing on you is a power overload. This can happen when you run too many accessories at the same time. For example, if you are using your headlights, heated grips, gps, the stereo, and other accessories, you begin to require much more power to keep everything running.
What causes stator to fail?
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.
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.
What happens when a rectifier goes 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. … If the regulator rectifier can’t moderate the voltage levels, the battery will overcharge. You can also use a voltmeter to diagnose overcharge.
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 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.
Will a motorcycle run 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.

Is a stator the same as an 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.
