I've had this mod for 3 yrs now but haven't used it for awhile. Back when I was tho after a few months of buying it the side with the chip just quit working. I had others so I put it up. Now the old lady needs one because she can't stop breaking shit so I'm trying to save a few bucks and fix it. Plus it's a great mod. H It's basically new, everything works but it won't fire. It reads the coil, counts the seconds of the puff, everything but it's not putting g power to the contact pin I'm guessing. I took it apart and checked out what I could see since you can only take off the very top and bottom squares, and could see nothing wrong. If anyone has any ideas it would be much appreciated.
