I Am Puzzled!!

[sos2001]

It seems that every dual coil nickel build I do ends up with an intermittent short. I put the build in, put it through the routine. Checks out fine on the ohm meter...put the chimney on...recheck for a short. Put it on the mod...set the resistance...it's good. Fill the tank...one last check..fine. Vape for a bit and "short!" shows up on the screen. Then it will fire again. Pull out the deck...screws are tight...nothing touching. Good on the ohm meter...good on the mod...reassemble...recheck...good. Vape for a bit.....yep, short shows up again...and then it fires fine.

Happen the exact same way on the Billow 1&2, Goblin. I keep the coils well above the air holes and have zero issues with a kanthal build. AND my single coil nickel builds are lovely and work flawlessly even if I say so myself...

So color me puzzled. I'm open to any suggestions as the dual coil builds put out outstanding flavor.

Using 28 ga nickel....2.5mm dia....11 wraps....07 ohms

This would probs be better in the temp control sub-forum..

anyway, which mod??

my knee-jerk response is that the resistance is lower than you think or that your ohm meter is telling you. Frankly, most ohm meters are useless with these kinds of resistances. If that build is actually 20 or 30 mOhms lower than it reads, most mods are going to belch it out with a low ohm or even a short error...

I'm guessing its the resistance also? Some of these mods have a 0.065 minimum and you are close to that. I would either get a couple more wraps on each coil, try 30g or try titanium.
