For future problem solvers, my 2003 Maxima brake and battery lights were flickering. The lights were eventually solid with no battery charge leading to believe an alternator problem. Went through the process of replacing the alternator with a remanufactured unit from Advance Auto. I got everything back together and the battery still wasn’t charging.

I realized the Alternator ground bracket was corroded as can be. Being my first time diagnosing my electrical system I’m now understanding the need for all clean & tight connections. I ended up getting out the multimeter to test continuity and it was so corroded in many spots there was none. I cleaned connections with a silver wire brush on drill brought it from 4v to 14.5v on the new alternator.
