Yep. Almost certainly alternator.
That Christmas Tree thing really scared me when I got my car first, thought everything was faulty.
You could do like Randy did, and get an uprated rewind while the alternator was out.
BTW, the guys who fixed mine only needed to put in bearings. If the bearings break, the windings can hit the stator, hence the fairy lights. Fix was cheap at about $100.
