Hrmm...It was a contact coil but it was a very good strong connection. I was building on a Lemo and I had it centered in the holes. And I was thinking the same thing so I went it and made sure everything was tight. Well hell. I knew I should have came here first....
Oh, and it was the Vaporshark rDNA40.
Brandon was answering a question about a DNA 40 mod not recognizing a Kanthal build in this
Vapour Trails TV interview starting at 53:31. However, even given the fact that your symptoms are different the underlying cause of your woes is more than likely the same. The DNA40 chip needs to be necessarily much more finicky about resistance changes from connections and builds than the other chips we are used to using because the chip uses those minute changes to calculate temperature.
Since MOV was so nice you might want to return the favor and send them the link to Brandon's interview which contains quite a bit of useful information. There is a high chance that they have pulled properly functioning rDNA40s.
Is anyone else bothered by the fact that the battery level indicator on these is useless???? Just wondering
I included a quote from Vapor Shark about the rDNA40 battery meter in this
post. Basically, in temperature protection mode the meter calculates remaining battery life using the amount of power that is being used when you release the firing button. If temperature protection has reduced your watts to a low level the remaining battery life showing will be wildly optimistic. To get a more accurate reading take a short draw and let up on the firing button while still inhaling. That should give you a reading more closely based on the power you are actually using.
