Resistance in wiring generates heat much as the filament in an incandescent light bulb gets bright and heats up. Probable resistance in this case indicates that the wiring is bad or inadequate, probably due to corrosion inside the cable sheathing where you cannot see it. The part that melted at the battery end was probably the weakest point in the cables.

90% of starter problems are bad connections. remove and clean both ends of the battery cables, so that they are shiney, also the cable from the solenoid to starter. check for nicks in the cables. and make sure the connectors are on the wire good. the cable tend to corrode from the inside out, if nicked, corroded wires, and connections, heat up and cause resistance to the follow of electricity, thus the starter doesn't get enough. you can also take jumper cable pos battery post to large post on starter. with a good connection, the engine should spin. then if the starter is good clean everything and retest. then trouble shoot solenoid. starters can be rebuit at a starter/alternator shop, much cheaper than a new one.
