View attachment Fuseable Link 010.jpg

Had a short when replacing dash lights...
So...replaced the suspected first fuseable link and added an inline 50 amp fuse block to it...but still nothing...have head lights but no other power to the car...ignition will not turn etc...here is a photo of another fuseable link...can someone tell me the correct name of the white plastic connector and also where I am going wrong?...when I put the new Packard connector in I tested all the Packard paddles with an electrical tester and none of these paddles had power...Marla
