my v3 stopped working 2 days ago. the oled screen reads, but on ohms it reads 9.9. this tells me there is no contact to the coil. i have a n mini and a full size nautilus and both tanks do this. anyone have any ideas? my new v6 should be here tomorrow and i'd like to repair my v3 for a backup. i have tried new coils and making sure the tanks are making contact to the mod.
