How to try a multimeter motorcycle stator
If you are passionate about motorcycles and find yourself facing electrical problems, the stator is possible to be the culprit. The stator is an essential part of the electrical system of the motorcycle and, if it does not work correctly, it can affect the general performance. In this article, I will guide you on how to try the stator of your motorcycle using a multimeter.

What is the stator and why is it important?
The stator is a fundamental part of the loading system of a motorcycle. It is inside the engine and generates electrical energy when the motorcycle is running. This electricity is used to load the battery and feed other electrical components. Therefore, making sure that the stator works properly is crucial to maintain the electrical health of your motorcycle.
✅ Main function of the stator:
Electricity generation function
The magnetic motor stator is composed of coils and an iron nucleus. When the steering wheel (with permanent magnets) turns at high speed, cuts the magnetic lines in the stator coils and generates alternating current for the use of the entire vehicle.
Energy supply
The generated alternating current becomes direct current by means of a rectifier, which loads the battery and supplies energy to the lighting system, the ignition system, to the instrument system, etc.
? Composition of the stator structure:
Iron core body: It is normally formed by stacked silicon steel sheets, which act as drivers of the magnetic field.
Window coil: It is formed by a copper wire winding covered with high temperatures paint, which is responsible for the generation of electricity.
Output cable: Connect components such as rectifier and lighter.
Mounting support/base: It is used to fix it inside the motor housing.
Opposition of the ignition system
In some models, the ignition coil is integrated into the stator and is used to generate high voltage impulses that activate the ignition and allow the engine to function smoothly.
Necessary tools:
  • Multimeter
  • Motorcycle Service Manual
Steps to try the stator with a multimeter:
  1. 1. PREPARATION:
    • Make sure the motorcycle is off and disconnect the battery.
    • Check the service manual to know the location of the stator in your specific motorcycle model.
  2. 2. Multimeter configuration:
    • Set the multimeter on the resistance scale.
    • Connect the multimeter tips to the stator cables.
  3. 3. Resistance between phases:
    • It measures the resistance between the stator phases. Compare the values obtained with the specifications of the Service Manual.
  4. 4. Resistance between phases and land:
    • It measures the resistance between each phase and the chassis of the motorcycle. Make sure these values are within the recommended limits.
  5. 5. Voltage CA:
    • Connect the multimeter to the Voltage scale CA.
    • Start the motorcycle and measures the voltage generated by the stator. Verify if it is within the ranges specified in the manual.
  6. 6. Comparison of results:
    • Compare the results obtained with the specifications of the Service Manual. If you find significant discrepancies, the stator may be defective.
Testing the stator of your motorcycle with a multimeter is a relatively simple but crucial procedure to maintain a healthy electrical system. Always remember to follow the instructions of the service manual of your motorcycle and, in case of doubts or problems, consider the help of a professional. Maintaining the stator in good condition will guarantee optimal electrical performance and a driving experience without problems. Enjoy the road with motorcycle confidence!
