HELP!!! Have a short SOMEWHERE 72 240z

Oh so wise Z community! 

I need your assistance desperately! I have a short... Somewhere! 

I currently have, running lights a all at night, I also have no dash lights, marker lights, tail lights, or engine light. I believe the dome light is also not working. 

What I do have is headlights, turn signals, brake lights, map light, and radio. 

When I change the fuse (tried 3 times) it immediately flashes and burns.. So much so that I burned my finger. 

Oh wise ones! You direction and help is very needed! 

Thanks much! 

Kira
