I had similar issue with my brand new Smok Cloud Beast RBA deck, my problem was the build quality was poor, the design had a silicon sleeve to isolate the 2 posts in the centre but it was out of line and the 2 posts touched causing a short, I am pretty competent when it comes to fixing things and I was too impatient to send it back, so I had a go, sorted the alignment issue and fitted the silicon sleeve properly, rather pleased with myself I tried it on my ohm's tester - FAIL!
The 2 posts still touched ever so slightly, you could wiggle them and the ohm's jumped all over the place, determined to fix it I used pliers to pull the gap open.
Success! I got the gap open alright
FAIL only because I snapped the post!
now bin fodder.
Rather upset I had no RBA deck and didn't want to use the ninja b**stard coils that came with it I resorted to buying a new one from a local overpriced store.
Tweaked the coils, wicked it up, went to fit it only to find the RBA outer sleeve had cross threaded at the top!
Bin Fodder again! - luckily I fished the other dead one out of the bin and used the outer sleeve from that and it now works.
One last thing to mention, the 2nd one I bought had a better post design and a greater gap so that won't short.
I love and hate Smok - if it wasn't for my precious T-Priv mod it would mostly be hate.
