You said your battery light flickered? Check the connection at the back of the alternator, i've had my wire seperate several times, which in turn wont charge the battery. If its corroded off (or even loose) then disconnect your positive and negative terminals and fix the connection and re-attach it. If everything seems in tact and securly connected on both battery and alternator connections then im willing to put money down that your alternator is cooked. Damn focus' are famous for poping these things <_<
