I have a 2004 ford f 150 and when I trun the key, all I get is clicking sounds. Even when I have it in accessory mode, the lights and radio doesn't really work. Everything has been working great since I bought it. Yesterday I had a new stereo, subs, and speakers installed all day. When I got the truck back, the guy said to keep it running for about 15 min because battery was weak from all the work on it. So I did, I think. But now I think the battery is dead and it won't start. What do I do?
