Got my Stick V8 Baby from a buddy of mine a couple days ago. Was working fine up until yesterday morning when i went to charge it. The charging light flashes and when i go to take a hit it flashes 4 or 5 times. I have installed a new coil, i have cleaned everything i could, and nothing is working. The only thing that helped was when I banged it off my hand a few times and it worked for about 10 mins.
