Audio Systems: Car Stereo, 2002 suzuki xl7, cell phone charger

Question
My son drives a 2002 Suzuki XL7 and had a stereo system installed a couple of years ago.  He uses his lighter to charge his cell phone and when he doesn't have the charger in the hole he will put the lighter in there just to keep it tidy in the car.

Yesterday he pulled the lighter out and plugged in the cell phone charger but the coil came out of the lighter without him realizing it.  He noticed the charger wasn't working so he looked back in the hole and saw the coil stuck inside.  He took a pencil to remove the coil and when he did he heard a grinding/popping noise and then  the stereo did not function.  He got the coil out but the lighter area didn't work either.  He checked the fuses and they were okay.  The stereo also has a large fuse on the line---could that be the problem?  Do you think that when the stereo was installed it was tied into the lighter?  We aren't sure where to turn.  THANKS FOR ANY HELP YOU CAN PROVIDE!!

Answer
No, there is another fuse that you haven't found or, heaven forbid a wire has been burner out.  You need to take the car into a repair/installation place. They will track it down in an instant.  

I recommend you not fix this by yourself because there are too  many fuse and wiring conditions in modern cars for the amatuer - unless you are trained in such matters.

I don't think the fixing charge will be more than a few dollars for this one, but you should make sure it is done right.

PS: All this being said, if you ARE electrically literate and have a VOM it is real easy on an automobile to chase down the wiring and find out where the voltage is lost by starting from the battery point and determine where the break occurs.  However, there are several hidden fuse ports in all Japanese cars; fuses that are not in the main fuse boxes under the dash and under the hood.  In any event, double check the fuses again; refer to the diagram in the car manual as to which fuses operate which sections of the car.  Sometimes a fuse will look good to the eye but is not.
