Just came in the mail earlier today. It's by the company EHPro. When I was done building it, my Tesla read "short" and the resistance read 0.0 ohms. I thought something was screwed up in the coil, so I rebuilt a new one. Still reads the same. So I thought it might be my Tesla. Threw it on my friend's iTaste SVD, and it did the same thing. Or rather, did nothing. and my Tesla still fires my basic drip and my iClear 30. Then I went to put it back on my Tesla, and it actually fired when it wasn't completely screwed in. It was maybe halfway in.. very loose. And it doesn't fire consistently because of how loose it is. Is it possible the connection is somehow messed up? It seems when it's fully connected is when it doesn't work. But seeing as how I can't actually see what's touching when, I can't figure it out.
