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.

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.

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.

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 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.

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.

An ATV uses what is called a stator system or magneto system to charge its battery. Any time the engine is running, the stator is continuously generating an electric charge. Some of the electricity is used to power the bikes different electrical components. What’s left is being used to charge the battery.

Never Forget to Replace Your Stator’s Connectors Connectors are one of the major causes of stator failures. A bad connection results in heat, and heat melts the connector, creating a short circuit that may fry your stator and other electrical components.

This is caused by resistance. Resistance is caused poor or under gauge wiring or bad connections. Check the ground at the frame crossmember just under the back of the tank. Make sure the connector between the stator and the R/R is tight.

Replacing the stator is not too complicated and requires a socket set and some heat resistant gasket repair silicone only. On 2006-07 Honda Fireblades the stator is located on the left hand side behind the crash protector.

A good stator will read over 28 volts. If the volts read lower than that, you may need to replace the stator. Visually inspect the stator for burnt sections or evidence of overheating and address these issues if present.

In general, there are two primary ways that the regulator rectifier can fail. First, the diode can burnout and cause the battery to drain. around 13 volts, the bike will start to drain the battery. When this happens, it’s only a matter of time before the engine stops completely.
