I have a similar post but didn't really receive any help so I'm trying a little differently. I have two smok micro tvf4s and one baby beast and the BB is the 3rd one 2 start registering ohms completely different after just unscrewing and screwing the tank back on the mod. They will go from .3 ohms which is what I built them as then all of a sudden it will say short all the screws are secure the bottom of the coil is secure as is every other part. Then it will read 1.5 or 2 ohms then .6 basically all over the place and when I put them on the ohm meter it will constantly jump all over the place. These are the same builds I've used time and time again so I don't think it's me. The BB is working for now but that bottom pin which transfers energy from the mod has about 1/8 of play in it and move quite easily. My micro tanks won't register at all now but they started out just like BB is doing now they would work for awhile then I'd have to screw and unscrew 20 or 30 times to get it to read right. I'm at a loss and could use some help. I'm about to just buy a new tank but if that's not the problem I don't want to. BTW the BB is only 2 mos old.
