I am new to vaping and have been using a Kbox 40 with an Atlantis tank set up. I purchased this tank primarily for the "plug and play" aspect of the atomizer. You simply unscrew the bad one, screw in a new one and you're good to go. However... I have been unsuccessful in trying to replace my old atty. I screw in the new one and nothing happens. I am not getting the flashing lights on the mod which would indicate there is a connection problem somewhere. If I put the old atty back in, it works just fine. I have tried to use all 5 of the replacement coils that I purchased. I can't believe that all 5 would be bad. Any suggestions?
