Thank you dude! I just checked and it looked like there was a contact point on that part of the coil. I used a toothpick to correct and quickly fired it up at 15W and no more glow or apparent hot spot. I fired it dry but I’ll try it again tonight with a load. Thanks for the tip!
I'll take the opportunity to use your example for our weekly safety reminder, but please don't take it as if it was aimed at you in particular.
You see guys, this is precisely the kind of situation where if he was using a mechanical mod (i.e. with zero electronics nor regulation) it could have been a potential disaster. It's pretty easy to create partial shorts like that on rebuildable attachments. When this happens, and especially on such a tiny fraction of the coil loops, you are basically shorting your cell.
This can easily overload the cell and exceed its maximum discharge current rating. The cell gets hot pretty quick and when it reaches the critical point, it enters thermal runaway and vents, catch fire or worse explodes.
Bottom-line: never ever use mech mods, they are not worth the risk and are not necessarily that much cheaper than regular mods nowadays.
