A bad battery or a poor connection will limit the voltage to the starter solenoid. This will be enough to make it move so no noise will be heard. The little wire to the frame is improtant to make the key switch and accessorys work. A poor connection will get hot. The melted plastic is a red flag and shows that this connection is supplying current and is needed. A battery with no capacity will have 12 volts with no load but will drop significantly when used. Test the voltage with the key engaged or the headlights on. It shouldn't go below 10 volts even while cranking. Battery cables can look good but still have a black coating that will disrupt the connection. If a connection won't come apart that is a sure sign of trouble. Baking soda and water is an excellent corrosion cleaner. Don't let any get inside the battery though (will neutralize the acid). The battery shouldn't run dead after only 2 days. Use a test light between the battery neg post and neg cable (with cable unhooked) to check for a drain. The dome light will look like a false drain so unhook this fuse first. Unhook fuses untill the light goes out to narrow down the circuit. An alternator diode can also cause a drain and it is an unfused circuit. Unhook the alternator charging wire (big red wire bolted on) if none of the fuses turn the light off. Also the battery can have an internal short that will cause it to run dead on it;s own. Check this by leaving the battery disconnected for a couple days then check its voltage. Hope this helps, Good luck.
