What does a stator do on a motorcycle

Will a motorcycle run with a bad stator?

The stator creates voltage that passes through the rectifier. The rectifier provides power for firing the plugs and also re-charges the battery. If the stator is bad, the current will be provided by the battery until it doesn’t have enough to keep the bike and all the electricals running…..which isn’t very long.

How do you test a motorcycle stator?

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 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.

What does a rectifier do on a motorcycle?

Modern bikes have batteries featuring electrical charging circuitry. A regulator rectifier is a standard component of this circuitry. The name of this part is appropriate, as a regulator rectifier regulates and rectifies voltage. Your bike’s alternator stator coil produces AC voltage.

How many volts should a motorcycle 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.

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.

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.

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.

Can a stator go bad from sitting?

Stators do not go bad from sitting unless the mag housing is full of water.

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.

Can a bike run without a CDI?

Yes, you can with a mechanical unit. But customizing one will take lots of time and effort. It might be even more costly to custom build one as the CDI on the market shelf is mass produced one hence efficiently produced. That will keep it’s price reasonably low.

Why is my motorcycle battery overcharging?

Yes, a bad regulator will cause your motorcycle battery to be overcharged. This is a common failure because of the way motorcycle alternators work. Measure the battery voltage while the engine is running. … If this regulator fails, then all that extra power gets pushed into overcharging your battery.
