    resistance jumping around on subtank plus - help

    Hi Guys
    I have posted this on another forum but to no avail so hoping to get a few suggestions here...

    as per thread title i received my subtank plus yesterday and removed the installed coil head as usual.
    I put a 3mm build of 24g kanthal wire, 6 wraps, and i came out at 0.9 ohms.
    This was higher than i expected but went ahead and wicked it.

    Anyhow, had a couple of vapes which were fine and then wham!! - horrible burnt taste.
    Checked the sigelei and and it was reading 2.2 ohms.
    Pulsed it a couple of times and it was jumping from 0.7, right up to 2.8.

    So i thought obviously something is not making contact correctly so pulled it apart, checked that coul leads were tight, and the contact pin at the bottom was screwed in tight.
    Tried again and same problem, although this time the fluctuations were less (0.7 - 1.8)

    The pre made 1.2 ohm coil reads 1.7, and the 0.5 ohm reads 0.8.

    Funnily enough i can also get the resistance to change by rotating the air flow control ring.

    This is doing my head in and if someone has a suggestion that i have not tried yet, please let me know.
    Cheers
    Edit - my billow tanks work fine on the same sigelei

    Sorry I can't help, my subtank plus rba is working great guns.

    Are the screws on the deck holding the wire down tight enough?

    That point about the AFC ring is interesting...
    Peace, YNWA

    Also hints from ECF Quote

    Remove the RBA from the base. Take a small screwdriver and put it into the center pin at the bottom of the RBA and tighten it up. It is most likely loose. This holds the top Positive side of the RBA together as well and it will throw off the ohm readings and it will not perform properly. Make sure you are holding the top pieces in the correct positions when you tighten the center pin.

    This seemed to fix everyone's probs both with stock coils and rebuilds

    As crisscross stated above ,this usually fixes the issue, What sort of power device are you using.????
    Ive had same issue ,but diff tanks, found that Attie centre pin was off centre and or base of atty 510 pin was touching ever so slightly the inside both positive pin and surrounding base (+ & -) on mod.
    Solved issue totally by removing attie centre pin and cutting a very slim delrin isolating washer ,re insert positive pin and making sure that the attie centre pin is tight and the head slightly proud of the last thread.
    Hope this helps.

    Thanks for the replies.
    Have just had a response from FT, they are sending a replacement base so we'll see how it goes.

    I got 3 x subtank mini and an original subtank that short my devices if i tighten (i have a habit of doing this!) all the way; which also give different resistance readings based on how tight the subtank is at times.

    I measured the inner wall diameter of the 510 pin bay with callipers and its roughly 5.54mm wide.

    I had a spare oring (spare for the bottom fed screw hole) from the russian, and it fixed one of them, for now..

    Put one of these orings through the 510 pin then guide it back into the beige insulator on the base - it should fix it from shorting.
