1994 Volvo 940 ignition chime won't shut off until key is p

I cleaned the battery cables and when reconnecting, caused some sparks. Since then the ignition chime will not turn off. (Very Annoying). I checked and pulled all the fuses and that didn't help. Im selling the car and am looking for a quick, easy fix. Any suggestions? (Cut or pull the correct wire maybe?)

all doors are closed and seat belts checked so that is not causing the chime. It has to be ignition key related
