Uhmm... I'm getting a "Check Atomizer" on mine when I top it with a Mega AeroTank - works fine when using a Nautilus. Attach the Mega on to an MVP 2 and it works fine. Nautilus works on the Hana Modz, as well as an iClear 30s. The Mega was working just spiffy prior to me changing coils and juice. Any ideas...?
Sounds like either the resistance is to low or not making contact with the positive pin.
