No, but it's pretty straight forward. I'm now getting 13.1v at idle with lights on, and 14.4v at 5000rpm. I installed it as the original, but with only 1 bolt with nylock nut in the left hole, it holds fine. I also had to cut a bit of the top left fins to make it fit without them hitting the plastic. All connections soldered and a new positive cable with fuse directly to the battery. I've already updated all my earth block, cables and frame earth with soldered cable lugs. If I get time, I'll pull the rear off on the weekend and take some pictures. Once you bolt the new R&R in place, you can sit the rear plastic on and you'll be able to see where you need to cut some fins off.
