I have had my BP for about 2 months and I have had this problem pretty much the whole time. I just didn't realize what is was until recently. I am kinda new to mods lol. I am learning rather quick. I have a connection problem. I have noticed a few times a day it just won't fire. I have come to realize that, it, I believe is the little wire that is connected by the screw when you open up the top, very gingerly of course. It has never been damaged in anyway. The reason I had come to this conclusion is because when I unscrew it maybe a 1/4 or even sometimes just an 1/8 of a turn and either leave it there or tighten it again it fires like a champ. Also sometimes it seems to be firing week even on freshly charged batteries. The same fix helps. Is there something I can do to stop having to play with the threads everyday. Thanks in advance for your time and advice.
