I don't know why the pictures appear upside down..
at any rate: I discovered that the PO hadn't cut any wires before the plug that connected the alternator to everything else, and it came with a regulator and rectifier and the wiring attached to those two pieces. I went to work making a quick wire harness so I could get it running. I borrowed a bunch of stuff from the CB750 that I'm working on, mostly because those pieces are 44 years old and could do with some replacements.
