There should be 3 terminals on the Solenoid. Two larger ones and one small one. The small one is for the relay switch on the firewall. The top large one is for the positive battery terminal and the bottom one is for the starter motor. The battery ground goes on the stud that is used to mount the starter to the engine.

Edit: If you installed the Neg battery to the top terminal you shorted the positive feed to the solenoid from the relay switch on the firewall. You may have melted the wire from the firewall when you tried to start it.
