What is a motorcycle stator

Can a motorcycle run without a stator?

only for as long as the battery has power to supply. The stator creates voltage that passes through the rectifier. The rectifier provides power for firing the plugs and also re-charges the battery.

What causes a motorcycle stator to fail?

A stator’s biggest enemy is heat buildup in the wire windings. … A failure of the rectifier function in the voltage regulator (also a part of the motorcycle charging system) can also cause high heat buildup in the windings, by preventing the stator’s power from being consumed by the motorcycle’s electrical system.

Can you repair a motorcycle stator?

Repairing a damaged or failed motorcycle stator is labor intensive, requiring careful unwinding and cleaning of the original stator core to prepare it for new wire windings. The newly prepared core is then carefully rewound, either using a specialized machine, or by hand, with high quality new wire.

Does a motorcycle stator charge the battery?

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 do you test a motorcycle stator?

First perform the static stator tests. With the ignition switch in the “Off” position, disconnect the regulator from the stator. Set the multimeter to “Resistance” or “Ohms” on the lowest scale, and insert one probe into one of the stator pin sockets. Touch the other probe to any chassis ground.

How many volts should a stator put out?

For example a 32-amp stator should put out 18 volts AC (VAC) per each 1000-RPM. At 2000 it should be 36 VAC (18×2). At 3000 RPM it should be 54 VAC (18 X 3). Each system has a certain voltage it should produce per 1000 RPM.

What are the signs of a bad stator?

Runs bad at lower rpms but runs good at higher rpms (Low speed coil going bad) Runs good at lower rpms but runs bad at higher rpms (High speed coil is going bad) Backfiring and just won’t run good. Sled slowly loses power during the course of the day.

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.

Can you clean a motorcycle stator?

There is nothing to be gained by cleaning the stator. You risk having the cleaning solution damage or remove the very delicate and old (30 years) enamel coating on the wires and causing a short. Just leave it as is.

What happens if 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 causes a stator to go bad?

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.

Why do motorcycle batteries die so fast?

All too often, motorcycle batteries die young, murdered by neglect. Dehydration, improper charging, and a slow discharge during storage all shorten a battery’s life. … To prevent these draws from killing your battery, you could disconnect the battery, but even if there is no load on them, batteries self-discharge.

Does a stator charge a battery?

What is generating its juice? 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.
