My Jeep Grand Cherokee decided to stop charging, but alternators are expensive! I went on ebay, and found a complete rebuild kit for $19 including shipping. It may not have been the best move, but eventually I got it all together and now it works great! This alternator is used on more than just ZJ's, so this is basically the same as Wranglers, XJ's, Dodge trucks, and a lot of other alternators.
