Alternator started sparking

THANK YOU GUYS!!! It finally happened, my electrical system is sorted out. Man, I feel like a huge burdens taken off my shoulders. I learned a ton from your advice here and responses to posts from 67Dart273 and Mattax. I thank y’all enough! I’m done learning for a while. Well, tomorrow I’m swapping in an 8 3/4 rear... We’ll see how it goes. I’m looking forward to mechanical work. I’m hoping it’s a choice next time I’m sorting out my electrical. Lol.
