I purchased the Lemo 2 and was using the stock .5 ohm coil for a day, when suddenly it would not fire. Checked my mod (iPV mini 2) and it said "check atomizer" and it read 0 ohms. Put it on an stick 30, same thing. Rebuilt the coil to .9 ohms on my ohm meter, but damn if my mod still can't read it. Suggestions?
