I just got a new vivi nova and a new ego-t battery. Straight out of the box -- no modifications or anything -- I did a couple quick dry burns to get rid of the factory residue and noticed the coil was only partially getting red. Only half of it was lighting up I thought it was weird, but went ahead with it (bad idea maybe). After a couple hours of use the new battery was fried. Won't take a charge, no light, no anything. Could a defective coil have caused that? Is that what happens if the wire is touching itself where it's wrapped around the wick?
