In the video it looks like the battery wire that connects to the alternator has a tab on it to hold it from moving. Normally that tab would go inside of a large plastic piece on the rear of the alternator that surrounds the battery terminal to keep it isolated. That piece seems to be missing on the replacement alternator, as you can see the stud and back of the case. With no isolator. I suspect that tab was hitting the back of the alternator and shorting the cable to the case.
The easy solution would be to add a second nut to the post to lift the cable and tab clear and be sure it can't touch. Or simply cut the tab off of the ring terminal so it cannot short the lead out. Oh, and thanks for the video.
