This is my first dna 40 mod. Bought it from Sweet Vapes the first day it was released.
Was extremely disappointed to see the issues with the wiring. However, hcigar did a very clean job on the wiring.
I rewired mine by just bridging, the existing ground screw to the open board hole. I hadn't even fired it off before and probably didn't need to do this since I don't push my devices, but didn't want any issues. Will probably attach an atty and try it tomorrow. Haven't fired it up yet.
I'm planning on using a SubTank-mini with the Ni coils, so we'll see how it goes. I'm not the neatest when it comes to soldering, but I think I have a good connection now to the board and the device fires up fine. I used solid copper wire (22 GA), and had a really nice fit before I soldered it. If nothing else, it has to be better than before.
This will be my first temp controlled device, so I'm ready to give it a try.
I'm installed/removed several atty's to it and my 510 connector only turns a bit if at all. I'll fire it up probably tomorrow and worry about the 510 later. I always carry an iStick with me as a backup so not worried about being able to vaoe.
Bigger question is, what happens if the 510 wire dumps? Does it short out the device, shock you. overheat, etc? I was just planning on using it until I had a failure from the 510.
Thanks folks
The 510 uses the case ground and should you loose or get a weak connection from the case ground you should get a Check Atomizer error message....
