That spade lug seemed to be a bit large for the wire gauge and I think that the crimp might have been loose creating the heat to melt the wire.
I was in the middle of a smoke for a birthday party and needed to get the smoker back up so I did not get any pics.
Fortunately I have an appliance repair shop a few blocks away, a couple of spade lugs and back in business, there was plenty of wire length to cut out the bad section and reterminate.
I am not posting this to bad mouth SI or start any post war, all I'm saying is that if you have owned one for 3 or 4 years you might want to pull the back panel off and inspect this.
Edit: looked on my bench and I still have the stuff I cut out on there.
