I recently bought my first high-end mod, ( besides my DNA200 ) the Gem, by Mark Bugs. Always been a huge fan of his style. However, I'm having some issues getting it set up. I get the coil installed, get the wick in, and test fire it with the included dry burn deck. At this point everything looks fine, it'll read in at .4-.6 right where I want it, but as soon as I install the deck back into the tank, something is shorting out because it'll drop down to .01 ohms. I have a feeling it's one of the post touching the top of the vape chamber, but cannot for the life of me figure out how to remedy the situation. Any help would be much appreciated!

not familiar with your set up but things to check as a general rule of thumb would be: make sure and TUCK the legs of the coil after its cut and wrapped on the post. make sure your coil itself is NOT touching sides of a chimney or ANY other metal surface. make sure coil is NOT touching deck. also, check your ohms BEFORE you put your unit on the mod. TIGHTEN your screws where your leads sit. make CERTAIN your wires not accidentally cut. make CERTAIN your ohms are NOT too LOW. usually a short is one of these things.. Hope this helps
also, if your coil IS touching sides of a chimney or metal, you can compress the coil a bit with tweasers and a little flame. let coil cool and give it another try. that should bring the coil in enough to clear the metal. hope this helps.
@realsis thanks for the reply, I do literally all the thing you've mentioned but to no avail :/ I think once I go into work tomorrow I'll try it again with a smaller gauge wire, I'm almost positive it has to do with one of the post touching the roof of the vapor chamber. Hopefully by using 28 instead of 26, the post will screw down enough to no longer touch.
You don't tuck the wick on this atty. I don't have one, but I've had Squape Rs.

@roxynoodle i understand you don't tuck the wick, I'm not sure where you got the idea that I do? And I've been slowly making my way through the GEM thread, but haven't found an answer to my problem. Waiting till I can actually post in that thread to ask directly. Thanks for the reply though
That was to the member who told you to tuck it, not you. I think I misread the post though.
I'm not sure how the coil on it could touch anything but the deck though. Do you have the coil down in the hole or sticking up off the deck? If you have it raised, do a second resistance check with the chimney on and you may have your answer. It could be touching the top of the chimney. If that's it, you need to lower the coil. I put my Squape R coils in with the leads on top.
Cut off wick flush at both ends, lightly tuck to fill vertical channels. Coil in the down position. Note that the positive pin is slightly higher and some have had shorting problems with 26 gage wire where the head of the positive screw touches the inside of the bell chamber. I use 28 gage, 6 or 7 wraps 2.4 mandrel no problem.
@roxynoodle ah lol sorry for the confusion! I don't think it's an issue with the coil, because the top of the posts are about a millimeter or two taller and even then, one post is higher then the other one. Which is why I feel like that is the culprit. And after messing around with it I've tried not pushing the deck all the way into the chimney, and it reads the normal resistance. However, it prevents me from tightening everything down which makes the AFC ring spin freely, causes leaks, and just doesn't look good all gapped out. So I'm guessing 28 gauge is just too fat and doesn't let the post screw down enough which in turn, is causing the short. Hopefully when in allowed to post in the GEM thread those guys will be able to sort it out 
ah dude that's what I needed to hear! Thank you thank you thank you!!! So happy my hypothesis was correct lol.
@DoubleTap1 may I ask what the final resistance of your coils usually come out to? And what wattage are you vaping at?
@Rabbit Slayer true, this is an expensive atty, but in the world of high end vape gear it really isn't that bad. I see gear sold on FB for twice or triple the face value, mods going for well over 1000$. That being said, this is an incredibly well crafted tank, the thing is built better then my car lol.
