My BB stopped working! It simply wouldn't fire! I figured there was something wrong with the connection. I have noticed a buildup of grime around the top connector which I thought might be causing the problem, but after a thorough cleaning it still would not fire. I checked the
batteries and the battery connection to no avail. I replaced the o rings on the off chance that may have something to do with it. I had pretty much determined that the button had just stopped working and was about to give up hope when it occurred to me to see if the carto worked on another mod. It was a fairly new carto so it should still be good, right? I can tell you I've never been happier to discover I had received a dud carto! I replaced the bad carto with a good one and my BB is now working flawlessly again!
I just thought I'd share this story in case anyone else has problems with their BB. The lesson is...if your BB is having problems, check the obvious first. The problem most likely doesn't originate with the solidly built BB.
