I have 2 of the same setup, nautalis BDC tank and an iTaste variable voltage battery. One setup has worked perfect for months (we'll call it set A), but the second (set B) seems to have a bad connection to the battery. It will pull in only air, producing no smoke or taste at all, and doesn't seem to be burning the liquid (I can usually hear it).
When checking the connection, the display says "non", while the other averages around 1.8. If I put the tank from set B onto the battery from set A, it still doesn't work. Unsurprisingly, the tank from A works find on the battery from B. So that narrows it down to the tank.
I clean both regularly and have tried new coils several times, I just don't know what else to do
Any suggestions would be appreciated!
