hey name is chase. I have a 94 f250 351. when I put the key in the on spot I blow a 50 amp fuse under the hood every time. I have no clue were to start can anyone help?

 

I can't say where, but 50 amps souds like a dead short..
A trick have used to find a short is get a 12v LED or a back up beeper horn and socket with long wires.
Replace the blown fuse with the light/horn and set the light where you can see it while moving
suspect bundle/wires around. The bulb/horn limits the current to not smoke anything.
If you move the wires w/ the short you'll know.
good luck
If your skeert put a small 2- 10 amp fuse in line w/ the light/horn.

 

thanks I found it
