i have a 04 fxst,bike was fine this morning parked it for a while,got back on and realized my speedometer wasnt working along with taillights and brake light,so i took the seat off found the accesorie fuse was blown,so i changed it.thought i was alright, turn the switch to on i could hear the fuse blow before i put the seat back on,i realize its probably a short just hoping some one can point me in the right direction.i took the dash off didnt see anything.

 

Did you do anything to the bike right before this happened? that is where I would start. If so, check all the connections on what you added. If not, it might take a bit longer. Maybe a wire was getting pinched by the seat or something.

 

I had the main do that. It was cut by the oil tank weld
