Something sus is going on?

i recently fitted a pulsar dizzy convinced i was pulling to many amps with my sound system and in turn draining my battery turns out the pulsar dizzy hasnt changed this. i thought maybe i should turn the sound system off for a while to allow the battery to recover maybe this is the problem but its not recovering and the alt is no longer charging at a decent rate(sitting at 12.6 where as was at normal charge) what could be wrong all my earths are fine and the battery water level is good. any help is much appreciated i gotta go to the showgrounds for vic uni exams tomorrow which is adding to my frustration along with the accelerator cable which jammed on full throttle with me the other day and another exhaust hole which i just fixed GRRRR
