I purchaced some 32 gauge kanthal and some fiberglass wick a little while ago to recoil my vivi nova heads. Tonight I got to the point where I had to finally do it. So I rewicked and coiled 6 atty heads. 5 of them I did 5 wraps and got inbetween 1.4 and 1.6 ohms which is what I was trying for and the other one I wrapped 6 times and got 2.3 ohms. All 6 of them seem to burn good, the coils burn evenly and I did not notice any hotspots. Now to my problem. As I finished each head I would test them on my evic to check ohms and to make sure the coils had no hotspots. Everything was good. I then put them on my twist and they fired same as they did on the evic. Then I tried them on my joyetech ego 650's, and as soon as I hit the fire button it would blink once really quick and do nothing. Then the battery would blink 3 times as soon as I took the atty off. I have 2 atty heads left that came with the novas that I havent used yet, so I tried them on the 650's and they worked fine.
