Sigelei 150W + Atlantis 2 Tank *Check Atomizer Error*

[Whitefox]

So I've been vaping the standard Atlantis tank with my SW150 for months now and to my surprise new coils came out! So I put the new .3ohm coils in and it says check atomizer... hmm. I readjust the pin on my atlantis tank and it fires! After a few days I change it out and another V2 Coil .3ohm wont fire no matter what. I figure I have to get the atlantis v2 tank for the new coils so I do and bam... new tank completely and wont fire. I check my spring on the S150W and clean it.. still no go. I try my Stillare RDA top at 60W and it fires fine.... My old atlantis tank WITH the v2 coils fires in my mech mod (just a single 18650 battery too). Does anyone know why the combination of Atlantis v2, with .3ohm V2 coils wont fire with my Sigelei 150w box mod? Its driving me up the wall at this point. (sorry for grammar, in a rush!)
