Found this tidbit on reddit
"The o-ring insulator under the iStick's centre connector has been squashed. When you tighten your atty it moves and shorts out.
Get a small flat screwdriver and carefully lift the centre pin and try and squash as much of the o-ring back underneath it.
It's a common problem with the iStick. If your atomiser's centre sticks out too much it'll break the rubber insulator."
I shut off my battery 'just to be safe' and got a mini screwdriver and moved it around nudging the o-ring under the edge of the pin. This completely solved my problem. It was also mentioned that the o-ring could be replaced "Number 60 O-Ring for a hardware store".
Since the reddit thread has some language that is against forum rules I am hesitant to post the link. If you want the link, just PM me.
