So I gave my VN 2.5 its first bath and dry burning, and now have my first dead coil as a result. No biggie since I've got enough spare heads to last me awhile, but wondering what I did wrong. I don't own an ultrasonic cleaner, and don't have any vodka or PGA or even white vinegar around at the moment -- I'm assuming beer, wine and/or balsamic would be just plain wrong for cleaning purposes heh heh. But the tank is dedicated to one juice so far, so I just gave all the pieces a good bath under hot running tap water. Shook everything out, patted the wicks dry with a paper towel, then left everything to air dry overnight.
When I got up this morning I did the dry burn. I gave it three bursts, 2-3 seconds each, with a few seconds rest in between. I could see the coil glowing on the second burst, and got a hint of a burnt smell on the third, so I stopped. Reassembled, refilled, and left sitting on it's side for about 40 minutes. The wicks looked well-saturated by then, so I gave it a try and I'm getting a very burnt flavor, beyond a dry hit type of burnt. This is with the 2.4 head, and I was running it at about 3.8-4.0 volts on a Twist. I tried tilting and swirling, also turned the voltage down to about 3.4 and the flavor was still very burnt.
So I assume I managed to kill the poor bugger? Prior to cleaning I'd used it sporadically for about a week or so, probably went through about 4 tanks. I'm using a thick and dark 60% VG juice, by the way, which I've read can shorten the life of a coil.
Any thoughts on where I went wrong?
