Smacksy, Dude, you've been around for awhile now. Why do you buy Smok? A guy on another site just did a tear down of one and found that they use the inner portion of a Jeans rivet for the positive connector in their 510. I know they are good looking mods and really feel good in the hands but the quality is just not there. Were it me I would send it back and get another brand. VooPoo, Vapresso, Think Vape, Hcigar, Lost Vape, Kanger, just off the top of my head are putting out reliable mods at similar prices. You can try wiggling the positive pin of the 510 connector around and see if that will eliminate the short.
