So I've been using my kbox mini for months now. Recently I have experienced a jumping ohm reading. My coil is at .56 ohms (tried it on a cuboid and a tarot mod) and my kbox is reading it at 1.0 and above. Then yesterday, it just stopped firing and the ohm reading is blinking at 9.99 ohms. I tried cleaning the 510 pin, pushing it up a bit with a flathead screwdriver and still no sign of firing. I just hope that someone out there knows how to fix this. I am pretty sure it is something with my mod because I tried my atty on a cuboid and a tarot and they both worked fine. Could it be a loose connection inside? I am pretty much satisfied with my kbox and it would be really sad if I have to replace this thing.
