Hello!

I got my first car last Monday, running perfectly, but yesterday evening when I tried to start it (it started fine 10 minutes before) I just hear this very fast clicking coming from the engine bay.
Lights, radio etc. were all working, I saw dash lights but just the clicking when trying to start.
Any idea what it could be? And how much money could I be expecting to spend?

Thanks,
Blade

 

Nevermind, battery was dead.
Jumped it and it started fine again.
