About 6 months ago I bought a smok Alien 85w with a TFV8 tank. The coils that were originally in the tank worked fine, eventually though, the coil got burnt and I switched it out with a different coil that came with it. Right after changing it I took a hit and it was burnt. Then I remembered that you have to wait 15 minutes after changing the coil to let the coils saturate. After that the coil worked but only for a few hits only at 20 watts until the coil becomes burnt again. Is this because I installed the coil wrong (there were plastic rings that came with the kit) or because I forgot to soak the coils for 15 minutes after replacing it?
