i wouldnt have even tried to fire a coil at .3 ohms from an evic, be careful man! i cant really help you with why its coming out to .3 ohms though not to knowledgable on PT rebuilds, only tried one myself. but possibly a short from metal contact?
Greetings and welcome to the forum. What are you wrapping your coils around? Are you using a drill bit, and if so, what size?
Regulated mods like the Evic won't fire below a certain Ohm level, on my Vamo it's something like 1.3 oHms. Your result, .3 oHms, doesn't sound right; it could be a short, maybe the coil is touching the metal cup? It's hard using 28 gauge for PT rebuilds, 30 or 32 gauge is much easier.
If you meant to end up with a sub-oHm coil, and you're new to doing builds, be sure to read some safety info on the topic: http://www.e-cigarette-forum.com/forum/blogs/baditude/4454-7-information-resources-your-first-rba.html

Try using Steam Engine | free calculators for your vaping endeavors as a guide. It's been very accurate for me. Sounds like a short though.
Thanks for all the help guys! I am going to try again with a smaller gauge. I was watching a video on YouTube and I followed it exactly but I don't where the problem was. I think it looked a little tight in there with 12 wraps so I am sure that could be the problem. I am nit sure the drill bit but it does fit in the slits of the atomizer
you have to be very careful that the sides of the post that goes down over the bowl of the atomizer head doesn't touch the coil as well. That will cause a short and give you odd ohm readings. Did you add a little cotton over the top for a flavor wick? It can help prevent the coil from touching the cap/post too.
12 wraps of 28g should come out at least somewhere around .7, that's with a 1 mm diameter and that's pretty small. with a 1.5od you would get somewhere around 1 ohm.

I've found 30g to be the perfect size to build my PT coils with. 10 (tight) wraps around a 1/16" bit gives me 1.8 ohms. Put the coil in the head with the bit in place (it fits perfectly in the slots). Gently pull one of the wires and bend it up. Put the insulator on the other wire, gently tug, then bend that wire up. Install the pin, then one more "slight" pull on both wires. Look at the coil (use a bright light/flashlight) to insure that neither leg is touching the side. If it is touching, pull on that wire again to get it straight. Cut the excess wire (as close as possible). Install the chimney then install the coil in something to check resistance. If OK, remove the chimney and install the wicks. Check resistance again after completely reassembled.
Hope that helps.
Edit: I always remove the chimney before checking resistance (with no wicks in place).

Here's a great thread....it will tell you how many wraps, what gauge wire to give you the desired ohms -

Good Luck to You.

Good Luck to You.
They are tricky to build at first. Try seven wraps and heat it up with a torch and compress it lightly. If it touchs the sides anywhere it wont work. If you clip wires and they stick out any at all they will touch the sides and not work. Twist of the wires in a circle instead of clipping them. I know your coilis hitting in one of those spots.
I've had good luck with 10-12 wraps of 30g Kanthal on a 1.5mm allen wrench. Torch and squeeze to get it tight. It definitely sounds like you've got a short somewhere, though. It gets a lot easier after the first few and once you get one working, you'll see why it's worth the hassle at first.
Hi,
I have read that Kanger uses 32ga kanthal for their coils (I use that same gauge as well when rebuilding the coils for the Kanger). I am able to get about 2.0 to 2.3 ohms with every rebuild. Maybe it's the gauge of the wire?

I am currently using 28 guage kanthal to do protank coos, and it's very tight but I'm getting a 12 wrap microcoil that reads 1.2-1.4 ohms. You must have the coil making contact with the cup part of the head. Take it apart, squeeze the coil together with tweezers, and when you put it back make sure that it isn't touching the metal or it won't work.

I use a 5/64 drill bit.....30ga.....8 wraps......2.1 to 2.2 ohms.....I remove the drill bit and insert a 1/16 bit to mount the coil in the "cup". The tricky part is futzing with the cotton but I eventually get a fantastic vape.
Make sure the ends you cut off after putting it back together are not sticking out. If so, when you tighten it down on an ohm tester or mod, the silicone squishes down and causes a short. Has happened to me.
