93 Mustang 2.3L no power - Help

My daughter crossed the jumper cables :mad: and fried the solenoid and battery; I replaced both the starter solenoid & battery and checked the fuses under the dash replaced a 20amp fuse. I reconnected everything and I turn the key I get nothing on the dash, no lights, bells anything?

What else could it be or advise what else I need to check?
