The battery, stator, and voltage regulator all work together...... If one goes bad, it can damage one, or both, of the other two...

If you've been through a couple voltage regulators in a short period of time... check both the battery and the stator before you replace another voltage regulator...

For example, let's say you have a bad stator, it's not producing the voltage it should and it takes out the voltage regulator. If you replace just the voltage regulator, without also checking the battery & stator, the bad stator will ruin the new voltage regulator in short order...

Obviously load test the battery, and search this forum.. there is a procedure for checking the stator with a voltmeter....

Good luck...

It really helps us to help you if you give us more to work on! What year and model is your bike? Have you had only one regulator fail, or more?
