earlier today I went and tried to start up my car and it wouldnt start. I had the battery jumped and it started. On the way home I turned on the switch to my radiator fan and the whole car just shut off. I pushed started the car and it started then went home. I just bought a new battery and it still wont start. I Tried to jump it with the new battery, no good. When I turn the key it makes a rapid clicking sound, I think its from the starter, Im pretty sure its not the main relay.

What could be the problem???
It seems like the car isnt getting enough power from the battery. The dash lights dim when I turn the key, and they turn off completely when I try to turn on the headlights.

Could be your alternator or just go to adv.auto and have them check your charging sys. Just giving ideas of what it could be.
