Nissan Repair: bose cd tape dont work, bose radio, fuse

Question
I just bought a 93 maxima and had to change the battery now my Bose radio don't work (it did a week ago before i bought it) can you asses me with this problem.

Answer
Anthony,

If you say the radio does not work at all and there is no noise you might have blown the fuse to the radio.  If yours has a security number that has to be entered when power is cut that could be the problem too.  Email me back and let me know when the radio stopped working.  Did it stop at the same time the battery was replaced?  If so, the fuse to the radio or amplifiers is probably blown.  These are very sensitive to voltage changes.  Also, I had one that worked but the presets were blown and that required a circuit board replacement.
