ok just working through the basics so others who chime in have more info
1) What tank are you using?
2) What is the resistance of the coil?
3) What metal is the coil?
4) What batteries are you using? Make and model...I.e. Sony VTC5A
5) what’s the charge like on the batteries...is mod saying they are full
6) Does the gold positive pin extend out the bottom of the threads on the tank ok?
7) Is the positive contact in the mod springing back ok when you push it down? Turn mod off first
8) Have you tried resetting the mod if it has this feature?
9) Not sure if the mod is firmware upgradable or not, have you done this to it recently?
10) have you ever had the atomiser leak all over the mod?
11) do you charge batteries externally or via the usb?
