The site won't let me put links but here's what i said in a previous post..
"So i've just finished making the box mod of Find My Vapes on Youtube that is called "How to build an Unregulated Dual 18650 Box Mod" with the only difference of having one 18650 battery instead of 2 and no fuses, but all the circuiting is the same. I've tested the voltage on the 510 connector when pushing the power button and it tells me i have 4.01 V and this is what it should be since the battery says its supposed to be 3.7V.. So up to now everything seems fine until I put on my new nautilus mini and i realized the atomizer wont fire and the coil doesnt event get hot and red. I tried 3 new different atomizers (two 1.8 and one 1.6) and still nothing.. I cant seem to find the problem and i've checked multiple times to see if everything is screwed on well... Can anybody help?"
