I rebuild my Pro Tank coils and have about an 80% success rate. I use 3mm silica and 32g kanthal wire. I'm no pro at this by any means. I have watched youtube videos and this is what I do when my Spinner (same as Twist, VV, but different brand) blinks after using a newly rebuilt coil:
1) Check where I clipped the wires at the base of the coil. Are they short enough and not causing a short in the circuit? I use nail clippers also, but sometimes, there is a wee bit of a tip left that is touching the battery when I screw on my Pro Tank. If there is even slight protrusion, I use needle nose pliers to mash them against the coil base (technical terminology is not my strong point).
2) If #1 doesn't resolve the issue, I take the base off, adjust the coil wraps and make sure they are not touching the coil seat and causing a short. I also double check that the wraps are not touching eachother or unevenly spaced.
3) If #1 and #2 don't resolve the problem, I cry and wail, and start over again.
EDIT ~
The more wraps you make the higher the ohms. If you have too few wraps, the ohms are too low and the battery has a built in mechanism to stop it from firing. Make sure you have at least 5 wraps.
