Vivi Nova tank not working on MVP?

[Purplepeeps]

I can't figure out what's going on. I've used the Vivi on my MVP before, with no problems. All other tanks are working on the mvp.

The vivi's working fine on the Provari.

Any suggestions?

I think I've heard a few people mention that the MVP's 510 pin sometimes moves down a bit. If the VVN is not firing at all, that could well beit, even if other attys are firing on the MVP. Either pull the MVP pin or the VVN pin a bit and see if that helps.

Thank you! It's driving me nuts!

Let us know if that works

That would be a center pin issue. It is an inherent problem of the 510 interface.

My crude drawing probably doesn't explain it well but here goes:

I've had a bunch of issues with vivis on my VTR. When it even reads it, it will read a 2ohm coil at 3.4 or something crazy and burns the juice. Every other tank or dripper I've had works fine on it, and the vivis work and read fine on my tesla. -_-

Very artistic .

What is it?

The tank pin is not making a conection with the battery, correct?

Well the red piece on the bottom is the center pin of the battery.
The red above it is the bottom of the bcc atomizer head.

The space between the two is the problem. The two pieces in red are supposed to contact; there's not much leeway involved.
If there is space between the two red pieces you get the problem.

Yes; the atomizer center pin not contacting the battery center pin.

The problem can be solved by filing down the 510 thread on the tank side so that the atomizer center pic literally sticks out and therefore has to contact the battery center pin before you run out of threads screwing down.

MVPs have a problem with the bottom red thingy in the drawing. Over tightening toppers pushes down the pin on the MVP. It doesn't pop up on its own. Take a stiff pin or needle and gently work around the pin prying it up as you go. The other thing is the pin on the tank gets pushed up. Take a paper clip, bend an arm straight and put it in the center hole. Try to tilt the clip and pull out on the pin to get the pin to come out a little. Saturday I flung a pin across the room having succeeded in pulling the pin out a lot.
