Smoked fusible link and ground wire

I'm looking for some help. I have a 70 Dart swinger 318 car. It sat for roughly 10 years. It supposedly ran when parked. I changed the intake, fuel tank, brakes all around, heater core and cleaned up some wiring. Today I went to start it for the first time. All the lights worked and the radio worked. When I turned the key it smoked the fusible link and and smoked a ground wire that was on a steering column bolt that ran to bottom of the steering column. I can not find anything grounding out anywhere. Thanks for the help!
