Hi all,
Sorry been super busy at work or I'd have replied to this sooner. Here's a WeTransfer link to higher resolution images (including one of the back).
It's not clear from the image still, but I'm pretty sure its not shorting out somewhere (though a multimeter is next on my list of things to buy).
