The MOD keeps asking "New coil (+)" or "Old coil (-)". It can't detect the atomizer due to the short circuit of your tank or your MOD.
• Please use a pin to stick on the 510 connector to see if it can be fixed or not. If problem still remains please refer to next step.
• Please try other tanks or coils with your MOD and try the same tank on other MODs to check if they could work fine, so as to confirm whether the problem is in the tank or the MOD.
• If it is the MOD issue, please try to upgrade the firmware of the MOD.
