Alt tested low at advanced.
Decided to replace alternator yesterday. Got the higher output carquest (I know that could be my issue now.)
Drove it quite a bit today (about 50 miles) and everything seemed great until went to leave the house again this evening. Battery light is now illuminating (very dimly) with no other issues. Drove about 30 miles like that and no symptoms outside of the light. Alt tested 13.2 at advanced. I know that’s low.
Do I just have a crappy new alternator and need to get an oem/denso? Also I broke the plastic cover for the wire that goes from batter to alternator (the one with 10mm nut) and wrapped in electrical tape. Can’t imagine that’s the issue but maybe worth noting.

Did you return your original alternator? If not, pull the brushes out and have a look. If you did, it wouldn't hurt to look at the brushes in the 'new' one. To me, this sounds like worn alternator brushes, which are $15-$20 and very easy to replace.
