I have a tesla 200w box mod with a mutation x v4. Just changed the coils from single 24g kanthal which would fire from 7w-200w. My new coils are Clapton coils I have them perfectly or as close to perfect as they will get in the rda all tightened down not touching the deck anywhere. My question is they will only fire between 7w-60w anything higher then 60 my box mod reads "!atomizer short!" I don't understand why it won't fire at higher wattage which I really need it to because it's a thicker coil which I feel like I should be firing at 70w-100w for best results. What would cause this please someone help, they are reading .10 ohms btw don't know if that helps
