Kayfun Light build, PROBLEMS!!

[quincey43]

I have just received my second kayfun light (clone) and whatever number of wraps I do it always comes out 0.07 on my ohm reader! I am using 28g Kanthal with 7 or 8 wraps trying to get 1.4/1.5 or thereabouts. I have the exact same kayfun which I have no problem building what I want, it's so FRUSTRATING!!!! The only thing I can see that is different is I am having one hell of a job to get the screws to keep the wire in place which I don't have on the other one. I tried my MVP to read the coil in case it was my ohm reader but no, it would'nt even show anything on that, HELP PLEASE!

Sounds like a faulty atty, does it still read 0.07 ohm if you disconnect one end of the coil?

[collie2011]

Possibly a short in the atty somewhere but that is as far as my knowledge goes.

It'll be the post screws............You can get replacements.

Replacement post screws

sounds like that could be the problem

It would only be the screws if the heads are shorting on the chimney or the positive one has gone right through the insulator (v unlikely). You can tell by the resistance going that low when you fit the chimney, to fix either get screws with smaller heads or out an o ring between the two parts of the chimney.

I havn't got as far as putting the chimney on yet! will try some new screws. I will compare the two decks when I have finished my tank on the Kayfun I CAN build on without a problem and see if I can see any differences with the decks. I thought I was doing really well with my builds (still a newbie at it) it's driving me mad!! and not being one to give up easily I can see me sat at the table for hours!!

Dont't know but I will try it

Also try stripping and cleaning......i had similar problem after drilling air hole out

[reefcat]

Always had to clear a little bit of swarf from mine, so agree with a full strip & clean

Just check that your centre pin is making full contact with the centre pin of your mod - this may cause a partial connection.
Something else you could check is that the larger of the two sides of the deck hasn't slipped to one side and is touching the smaller side; this will cause a short no matter how everything else is. To fix this, remove the coil, and with a screw driver loosen the centre pin slightly to allow you to straighten up the larger block so that there is a gap all the way through. Whilst holding the block firmly in place, tighten up the screw so that the block is secure, but be careful not to over-tighten as some centre pins are rather fragile and have been known to snap under tension.
Let us know your progress, and if you can, take some good close-ups of the build so that we can see what you've done. That would help us no end

EDIT: something else which has just occurred to me. Check that your coil is proud of the deck below (where the airhole is), and is also not touching either of the screws or posts. I've only mentioned this as the same problem caused me no end of grief until some kind soul pointed it out to me! Check too that any tails left after trimming your coil tails are not touching anything that they shouldn't.

Good call, sounds most likely cause to me

Checked the deck and the large side if definately square and not touching the small side. The coil was sitting ok and not touching where it shouldn't. I even tried two pre made coils in case it was my build but they were the same. Also checked the centre pin and seems fine, I have put it away for now before it end up through the window!! I will email the vendor and see what they say. Thanks all for your suggestions but need to calm down now!

[chykensa]

Hmm, if you've tried all the suggestions above, I wonder if there is a manufacturing fault and the atomiser itself is not constructed properly. I think a call to the vendor is now required, if only to save your glazing!

[quincey43]

All now sorted and seems to be working fine. I sent an e-mail to the vendor who got back to me quickly with most of the suggestions you all put on here. It seems the centre pin was screwed in too tightly and was squashing the insulator it was really hard to undo but made sure everything was where it should be and did'nt tighten it up so much put in a 1.5ohm coil and it works!! Thanks for all your help, so glad it's sorted I really like these.
