He found a replacement (see Post #17 and onward), I think the OP gets that he made a mistake. If not, I will remind him: Hey OP, you big dummy, I hope you learned your lesson! If not, it will cost you.
Or maybe it would be nicer, and more effective, if I were to say something like: Hey OP...we've all had those "oops" moments. To help avoid them, it's best to never make changes to your connections with power on". Yeah, that's what I'm going with. Ignore my negative comment,.
