ok so after a few days of studying and collecting all the various items i need, i finally set out to do my first RDA build today. i got the air holes in my igo-w drilled larger, wrapped my coils, set them in the connections, grabbed a fresh battery off my charger, popped my new build on my stingray clone, hit the fire button AND!!!...nothing...for some reason none of my tanks including my igo-w make connection with the top of my stingray clone accept for my nautilus. i put the nautilus on there and the thing vapes awesome, I've tried my RDA, and both of my iclear tanks and nothing happens when i press the fire button. I'm assuming its because they are not making contact with the floating pin up top. i made sure my firing button was screwed in all the way and tried to see if there was a way to screw in the floating pin on the top cap but there isn't. i have a feeling this is a lost cause and I'm just gonna have to wait until i can buy a new mod to start rebuilding which is extremely disappointing to me but does anyone have any tips or tricks i could try?
