I'm having some issues with my SVD. Luckily I have more devices to use. I put a newly charged battery in the SVD and I put a tank on it. Turn it on and take a vape. When I hit the fire button, sometimes it lets me take that one toot but then it will shut itself off. When it shuts itself down, it will give me a 0.0.0. message and then show what my wattage is set on. I've tried different batteries and different tanks. I just turned it on again, unlocked it, checked the ohms on the tank, and then I got the light show and it shut itself down again without me hitting the fire button. Any ideas?
