Hi. I am currently using an Arctic tank on a coolfire 4. I vape at around 35W usually. I went to change coils from the coil that came with it to a BTDC .5 ohms that I purchased at a local vape store. Once I put the new coil in, my coolfire kept saying check automizer. I tried tightening the coil. removing and replaceing the coil. I double and triple check that it was .5 ohms and not .05 ohms (as the coolfire cant read below .3). I just don't know what to do. It will not fire at all. I had to go to a different store and buy a different coil. Now im left with two BTDC coils that wont fire on my coolfire. Help?
