How to test a motorcycle stator

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.

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.

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.

What happens when the regulator rectifier goes bad?

In general, there are two primary ways that the regulator rectifier can fail. First, the diode can burnout and cause the battery to drain. You won’t have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. … around 13 volts, the bike will start to drain the battery.

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.

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.

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.

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 a stator cause overcharging?

About the original question- the stator AC voltage output is an rpm limited commodity. The more it spins, the more the juice flows. (Typically, a bad stator won’t put out excess electricity.
