.The voltage regulator is inside the alternator. It can be replaced. With the battery disconnected and alternator removed, mark the case halves with a magic marker so you can assemble them correctly later. Remove the four screws that hold the case together and separate them. Don't be alarmed when the brushes and springs fall out. The back halve will contain the regulator. Remove the screws holding the reg in and replace the reg with a new one. This is a good time to check the condition of the brushes and replace if necessary. Using a straightened out paper clip you can hold the brushes in place. Notice the small hole in the back side of the back half of the alt that allows you to insert the paper clip thru and hold in the springs and brushes in place while you assemble the two halves. Once assembled with the four screws you can remove the paper clip.
