Car wont start

I had a short somewhere that kept blowing my alt fuse and i dont have time to fix it, so I took it to ford dealership to get it fixed, they said it was teh alt and cost 270$ to fix. My dad drove it to my apartment 40 miles away and it was fine. The electric lock worked fine then I tried to start, it clicked once then nothing. Now locks dont even work. I put charger on battery and its 50%. headlights wont turn on either. I gotta go to work so I can test anything now. But what can I do? Any ideas? I'm thinking a fuse blew somewhere..

Think the dealership will pick my car up and fix it again? Or am I ****ed?
 
i recently had a problem with my starter and it turned out to be a bad ground, what i had to do was run a ground from one of the starter bolts to the chasis


but it dosent sound like this is your problem since you said your lights wont come on. check all your fuses, electrical demon suck
