Alternator problem

The lights were flickering constantly. You guys gotta realize that the alternator was at least 30 years old and had been sitting for 20 of those years. I'm getting a set of new matched fan belts as one is tight and the other is pretty sloppy despite the fact that they are from carquest, ours has really high quality parts especially compared to NAPA, and the same length. I guess it's just a fluke.

When I got it tested it failed the regulator and the rectifier test.
