Default 2003 Trailblazer

I just changed the battery in the blazer but the voltage light is still on. I need some insight on what is the problem.

Another problem I have is that I have to pump the brake to get the blazer to go into reverse. Any ideas? Please help. Thanks.

The light is most likely on because the alternator is not charging.
