Hello! I have had my dab pen for roughly, 3 months now. I am on my 3rd coil, but I just ran into an issue like 15 minutes ago. I just got finished charging my battery, but when i screw my coil onto the battery and try and hit it the battery only works for like .2 seconds, so its impossible to hit it. I have connected the top of my hookah pen onto the battery, and it lights right up. I have tried rubbing alcohol w/ Q tips. I have no idea what to do, and I just bought my new coil like 4 days ago. So, basically when i connect my coil, the battery doesn't work. When the coil is unscrewed, or a different coil is in it works perfectly fine.
