electrical/fuse problem

Has anyone experienced problems with the fuse that controls the dome light/radio/dash clock/seatbelts in a 240sx? This fuse keeps blowing out in my car and I'm guessing it's a ground somewhere but I'm not sure. Any information on this issue would be greatly appreciated. Thanks

I'm no expert, but I had a problem like this and it was due to a bad alternator. I dun know, did you put in a new head unit or somethin that's consuming too much of the current?
