What I'm sure is that the + terinal of the bttery got melted because of a high resistance.
Hmmmm... what can you do now?
When the terminal is meltes you should have found the point where the problem is.
High current, bad contact --> hot
When the problem is anywhere else this could end up in too much resistance, therefore less current and a weak turning starter engine. But the melted terminal?
I would suggest to clean up the terminal and the battery pole. Maybe some copper grease would also give a help.
Checking the wires could also make things clearer.
Also have a look at the negative cable from the battery to the frame and the engine fixing bolts. If you have a multimeter connect it to the battery poles and measure voltage while starting. It should not be to much less than 12V.
The later Nordie versions have an inductive ignition which switches off when the voltage drops down below... sorry i can not remember the exact value.
Maybe someone else here has some better ideas
