Here's my ordeal. I soldered all the parts together, pressed the button, no hiss. I mentally tortured myself. I undid everything, got new parts and before I did anything, I read how to solder, then practiced. Then I went back and soldered all the parts. Nothing. Now I'm really upset. I decide to widen the slit in the pole that goes into the atomizer. Forgot to turn off the box. Spark!!!, okay, so I can't get the slit wider, so I bend the pole slightly to one side. I press the button . No hiss. I'm ready to cry. Wait, I see a glow. my ATOMIZER IS GLOWING RED!!!!!! I guess it's not supposed to. I tell hubby. He says what kind of wire you using. I did the positive wire that came with the battery holder. But ran out of the black, so I used 20 gauge 300 volt copper wire. Hubby says I can't do that. I know there's some of you laughing out there. So I will be re-wiring my negative wire with the wimpy one that came with the battery holder.
Hopefully my next one won't take 3 days to make.
That wire should not be a problem seminole. It's just a ground and ground doesn't care.
