What's wrong with my Ford? Besides it being a Ford lol?

I have an 06 Ford Taurus SE and I just put a new motorblower fan in so it can have heat again this winter. And it worked fine on the way home. And now its next problem is that when I left my place an hour after my friends place all the lights went dark even my cars headlights. The raido sounded off too. And when I got a block a away I can feel the Ford jump forward a lot since it was slowly dying then I noticed that my battery check light popped on and when I made it to my driveway all lights went out and its now sittinf dead amd don't know what to do. A friend says its my alternator is shot but not entirely sure.

Does have all the hallmarks of a battery using up all of its charge because it is not getting fed by the alternator. There are several reasons for that but without testing the battery and the alternator no one will be able to say for sure what the problem is. Could for example be a wiring fault

Maybe it failed cause you take lousy care of your cars, it would make sense if you hate it enough to make such a stupid joke.

Could be altenator could be serpintine belt broke
