warning chime

I have a 2002 chevy cavalier and ever since i replaced my stock radio i no longer have that warning chime go off when you leave your keys or lights on. I am pretty sure something is blown because i know i grounded out something when installing the new radio. I have checked all the fuses in the fuse panel and all are good. What i was wondering is if there was a way to check the circuit breaker that is in the fuse panel. Could there be a short which causes this breaker to be tripped? Does this have anything to do with the problem. If i could just get a wiring diagram i know i could get to the bottom of this but the haynes manuals are garbage. Does anyone know where that little warning chime comes from?

nothing is wrong, that happens on 2002 and newer (i believe) cavaliers with aftermarket stereos, to keep your chimes you need to buy a special, more expensive, wiring harness for your new stereo
