can you rebuild alternators?
I have a 87 ranger 2.9. My alternator light came on the other day. Had the battery check. They said it was good. Took the alternator to advance. And it was putting out 13 volts. They want around $100 for a rebuilt one. But could order the brushes for a little under $5. So, my question. Can you rebuild the alternator? And do you special tooks to do the job? This is the factory alternator it has been a good one.
