So I used the hardwire kit that came with the V1 and tapped into a wire (idk which one cause my friend did it who knows more about the electrical system of cars) Any way he had a thing that would test if it had 12v after it was hooked up. And the thing lite up meaning it had 12v. However when I plug the V1 into it it does not power up. I tried the V1 with the cigarette lighter and it worked using the same cord. What am I missing here as to why it is not working.
