Have vision twist been using a v 2 clear tank 2oms at 4.3 volts on it. This did not happen till just now noticed a click sound after I taken a puffed say 35 seconds apart and keeps doing it. No light comes on. So took off and put a cart on it and puffed no click noise after. Just put it back on and did it again after a puff. Did not happen till I puffed it again. No puff just hitting the button, no click.
Any ideas
