How to Troubleshoot a 12V 6 Coil Scooter Stator

Scooter doesn't have spark it maybe the stator 

A scooter stator is a crucial component of the electrical system that generates power for the scooter's battery and ignition system. If you are experiencing issues with your 12V 6 coil scooter stator, troubleshooting the problem is essential to ensure the proper functioning of your scooter. In this comprehensive guide, we will provide you with detailed steps to troubleshoot a 12V 6 coil scooter stator.

Step 1: Visual Inspection

Start by visually inspecting the scooter stator for any visible damage or loose connections. Look for signs of burnt or melted wires, corrosion, or loose connections. Pay close attention to the stator coils, as they are susceptible to damage from excessive heat or vibration. If you notice any issues, address them before proceeding to the next steps.

Step 2: Testing Continuity

Using a multimeter set to the resistance or ohms setting, test the continuity of the stator coils. Disconnect the stator wires from the scooter's electrical system and measure the resistance between each coil wire. Compare the readings to the manufacturer's specifications. Ideally, the resistance should be within a specific range. If any coil shows infinite resistance or significantly different readings from the others, it indicates a faulty coil that needs replacement.

Step 3: Testing Output Voltage

Reconnect the stator wires to the scooter's electrical system and start the engine. Set your multimeter to the AC voltage setting and measure the output voltage between the stator wires. Compare the readings to the manufacturer's specifications. Typically, a 12V 6 coil scooter stator should produce a voltage within a specific range. If the output voltage is significantly lower or higher than the specified range, it indicates a faulty stator that needs to be replaced.

Step 4: Inspecting the Flywheel and Magneto

If the stator tests fine but you are still experiencing electrical issues, it is necessary to inspect the flywheel and magneto. The flywheel is responsible for generating the magnetic field that interacts with the stator coils to produce electricity. Check for any damage, wear, or misalignment. Ensure that the magnets on the flywheel are securely attached and not cracked or broken. Additionally, inspect the magneto, which is responsible for producing the spark required for ignition. Look for any signs of damage or wear, such as loose wires or broken components. If you notice any issues with the flywheel or magneto, address them accordingly.

Step 5: Testing the Regulator/Rectifier

If your scooter is still experiencing electrical issues after inspecting the stator, flywheel, and magneto, the problem could be with the regulator/rectifier. The regulator/rectifier is responsible for converting the AC voltage generated by the stator into DC voltage to charge the battery and power the scooter's electrical system. Using a multimeter set to the DC voltage setting, test the output voltage of the regulator/rectifier. Compare the readings to the manufacturer's specifications. If the output voltage is significantly lower or higher than the specified range, it indicates a faulty regulator/rectifier that needs replacement.

Step 6: Consult a Professional

If you have followed all the steps and are still unable to resolve the issue, it is recommended to consult a professional mechanic or scooter technician. They have the expertise and specialized tools to diagnose and fix complex stator problems. They can perform advanced tests, such as insulation resistance tests and load tests, to pinpoint the exact cause of the issue. Additionally, they have access to technical resources and replacement parts that may not be readily available to the average scooter owner.


Troubleshooting a 12V 6 coil scooter stator requires a systematic approach to identify and resolve any issues. By following the steps outlined in this comprehensive guide, you can effectively diagnose and troubleshoot problems with your scooter's stator. Remember, electrical components can be sensitive, so it is crucial to exercise caution and, if necessary, seek professional assistance to ensure your scooter's electrical system operates smoothly. Regular maintenance and periodic inspections can help prevent stator issues and prolong the lifespan of your scooter's electrical components.
