    Basically, my V8-T8(6.6T) coil got burnt so I switched it out with another one in the box, the V8-Q4(5.0T). After about a week it just stopped working then my mod, Sigeli 230 watt, kept saying check atomizer. I thought it was a problem with the 510 connector, however, the other coils from the package work it's just the V8-Q4(5.0T) that doesn't work. I have opened my tank thoroughly and have checked out the coil its self. Nothing is wrong with it. I have tried to contact SMOK but they still haven't responded. Can anyone please help me understand this problem?

    Rub your finger around bottom of coil and check for a wire sticking out. It will ground out on tank. A magnified glass works wonders to see the little fine wires. Cut it back closer to the rubber grommet. But with eight coils inside I assume when factory built it the grounding out is done at the factory and is inside the coil which can not be fixed very easy. CHEERS!

    if it works with the other coils and only that coil says check atty then it is obviously the coil.

    Those coils must be difficult to manufacture, as this is actually a pretty common problem. If you are happy with the performance of the other coils, I'd suggest using them. If not, you're going to have to learn to deal with some wire snipping I think, it seems to be a common complaint for those coils. With the cost of them, I personally wouldn't buy them (not that I would anyway, I don't think I need an octocouple coil, though I am a non-DL/sub0hm vaper....

    Good luck,

    I would still think its a problem with the 510 pin. Every time you change a coil, you are removing the tank from the 510 connection so it may be getting contact sometimes but not others. It could just be that the 510 pin needs a good cleaning or it could have been pushed down so it's not making good contact or it could have a loose wire. Hopefully an easy fix or like you said just that one particular coil.

    I had the same problem with the same kind of coil 3 days ago. spent 2 hours trying to figure out what was wrong. finally switched it out with another coil and bam! worked without a flaw. the problem with mass produced coils is that occasionally i guess you just come across a defective one.

    I've had numerous smok coils over the years with this very issue.
