Default Smoking neutral switch on a curvy

So I have pretty much got my bike back together (I haven't put the fairings back on yet, and the bolt holding the can on sheared, so I have no can on it either).

Cranks over by hand fine, full compliment of fluids, so I think, well let's give it a whirl (battery may hold out or not) it turns over a couple of times, but stops. I try this a couple more times, but I think the battery it pretty much kaput. I then notice some smoke. It dissipates, but the wires from the neutral switch are warm, and one has partially melted the insulation (the black one if that means any thing).

I can replace the neutral switch no problem, but without knowing what caused this, I'm probably going to cook another. Any ideas of the root cause?

Dodgy earth strap perhaps so the starter current is trying to earth via the neutral switch?
