Is this my electrical short ?

If you have a voltage-ohm meter, you can set it to ohms and probe both of the socket contacts with one side while grounding the meter's other wire. If you get a reading of 0 at either electric contact, then that's your failed side. Track it down by cutting the wire off of the socket and checking just the wire again. If you still get a reading of 0, then the wire is shorted somewhere between the socket and the fuse box.

Good luck!
