Alright tried to do a little bit of searching and couldnt quite find what I was looking for. Just received this clone from fasttech sku 1552300. As far as I can tell the center post is just one piece, and seems to be incredibly hard to actually get a connection. Seems like the post goes in too far but you have to tighten it down so that the positive pin base? wont move. Like yesterday installed a prebuilt coil while it was on my mvp2. Actually showed the correct ohms and I thought holy crap actually got it right. Took the russian off and set it down. When I went and put it back on went back to showing 9.9 ohms.

It has a short, most likely. I'm not a fan of pre-built coils...but thats what you're working with. Yes, the pin has to be tight or the block will move. When tightening the positive pin, you need to make sure the block is straight or it will turn a little bit, making contact with the rest of the deck. That positive block needs to be perfectly aligned and not touching anything else. If it's even a little bit crooked, it will come in contact with the negative post and cause a short. You also want to make sure your connection screws are tight...they can loosen up sometimes after the first couple firings. The coil can't touch the sides of the chamber....the leads need to be clipped off flush. If the clipped lead sticks out enough to touch the chamber, that will cause a short.
There's a YouTube video, Vapechat! - YouTube, discussing the Russian 91% V2 center pin. I'm not sure if this pertains to you, but thought I'd post the link just in case.
I would start by pulling up on the MVP's center pin as stated above BUT on my MVP 2.0 when there isn't a connection being made the screen reads NON not 9.9. If there is a short the screen will read 0.0
My Polished 91% came with the block loose as a goose. The fix for me was to un-screw the contact pin and tighten the center pin that it screws into while holding the block and insulator aligned to the "fixed" block with a pair of fine needle nose pliers. Haven't looked back since.
Yea nothing is touching the sides and the blocks straight. Its just whenever you screw in the center post to tighten everything it just seems to go in to far and wont make contact with the battery. I know most say theres two screws for the center pin and ive seen pictures of those and mine looks nothing like those.
So what you are saying is, the contact pin does not unscrew from the center pin. Correct?
yes exactly. h**p://fatdaddyvapes.com/uploads/3/2/5/6/3256800/3877336_orig.jpg shows both pins. Mine looks like its all one piece.
If you unscew it to where the contact pin is just peeking out past the 510 threads does the insulator block become loose?
Ya.. I notice that when there is no tank on it, it'll read 'non'.. If I have a tank on and its not making a connection, it'll read '9.9'... Dunno why, unless its reading through some leaked juice in the 510 connection..??
I dont have it with me so I can't be sure. I want to say yes it will become loose.

When you get to it, try it. The contact pin has to be just peeking out below the threads to make contact. I'm only guessing here ( never had an MVP) but that 9.9 code you are getting may mean "no contact". If you do un-screw it and the block becomes loose, un- screw it all the way (can't hurt at this point!) and double check to see that the center pin is indeed one piece. My suspicion is that the contact screw is over tightened into the center pin. The only thing I didn't notice in your OP is where you purchased it from Fastech so in reality, it could likely be a clone of a clone. Report back with your findings! Good luck to you.
Im sure it means no contact, since it says the same thing on the mvp and on the lavatube. That last link i posted if you replaced the ** with http clearly shows the center pin as one piece.
What's happening is that the 510 threads are making contact before the center pin is making contact. Try my suggestion and see what happens. What do you have to lose?
Nothing to lose thats why I have already tried taking the center pin out and indeed looks to just be one piece.
Try a thin ss washer under the screw head.. It must fit w/o touching the sides though.. maybe an o-ring would work better, but you have to be able to snug the screw down good.
