Electrical problem...help!

[ALFA33boxer]

Hi everyone!
This morning I started the car and while I was waiting for the engine to warm up,I was trying to install a small fun (since is to hot & no conditioner) to the hole where the cigarette lighter is... and something happened when the two wires touched each-other. The engine nearly died for one second.
After that I put the stereo on but this last one doesn't work, there is no power, and the cigarette lighter is not working and probably something else won't work next.
I checked all the fuses and they look fine...
There is any other thing I should check...
Any idea what is wrong after the short connection

Thanks,
Elvis

Maybe any wire burn or fused whit other, or the contacts of a relay are "glued" whit the shot circuit.
If any fuse isn’t burn is strange.
Try take off the negative cable from the battery and whit a multimeter see the resistance between the positive cable and the negative, if any wire is fused whit any ground you will see that way
