last night i was able to get a coil at 1.9ohm using 32g kanthal. It was vaping great, i was getting plenty of vapor. Well today i was getting a couple of good vapes then it gets really harsh. Then i realized my ohms were jumping around from 1.1 to 1.9 random. I would check the ohm before every hit. First hit i was getting 1.9 then second it would drop to like 1.5-1.6 and by the time it gets the harshest i was getting 1.1-1.3. Can someone explain to me what's going on? Thanks in advance

check to make sure the positive and negative contact are tight. very common of ohms jumping around. I check mine at least twice a day.
thanks, its a RSST so i think the positive is okay. I saw a hotspot on the negative so i fixed that and tighten it. Now im at 2.0ohm and it seems to be staying there.
ya, my rsst did the same thing(its the only genesis style rebuildable with an insulated wick hole that i have) but i got that hot spot out and it works like a champ
i like the aga t better myself, the rsst is better looking though. dont have any high end rbas yet
can't justify spending big money on a zap or ac9, im quite happy with these ones. got a AGA T2 coming in soon.
Ive got this going on too with my aga t2
Its my first rba i got 5 days ago. Ive also noticed on my first coil that if i let it sit say overnight and checked the ohms in the morning it would read lile 4.0+ then if i hit it a time or two the ohms would drop back down to 1.9-2.0 immediately. It would then jump around from 1.7 to 2.3 more or less until i let it sit again for several hours and the ohms would go to 4+ again until i fired it.

The "wandering ohms syndrome" is the one negative issue I have with RBA's. It is because of this issue that I am not a fan of the ultra low resistance coils so popular with many users.
I agree.. Check this out, along with the "advice" he first gets: http://www.e-cigarette-forum.com/forum/rebuildable-atomizer-systems/417361-too-low-ohms.html
there's no ohm jumping around with a good steady setup.
depending on the wire you'll get an additional .1, max .2 ohm after a week or so: a wire that has not been annealed correctly before will expand a bit but it will not retract. You will never get less than the original resistance (as some mentioned) unless your setup is shaky or you're shorting somewhere.
A good practice if ur using ss mesh is to pre-coil on a tool, work out the exact resistance you need and electrically anneal the wire. Then slide in your wick and work out the "wick part" of the setup...

i still use carto and my twist when im out, its way more convenient than taking a huge mod with a huge RBA : D .
Generally, if your resistance increases, it's a connection issue; with either the positive or negative connections. If resistance drops, it's usually an issue with the wick.
It's possible my coils are shakey. I've only wrapped a total of half a dozen between two AGA T2's in about 6 weeks time, so I'm admittedly still a noob when it comes to RBA's. The Provari is generally pretty picky about shorts on it and throwing an error message my way. If it's happy I feel fairly secure there's no shorts in the coil.
I'm using pre-rolled, lightly oxidized mesh wicks from an online vendor. I wrap my coil around a drill bit and then attach over the wick on the AGA's and check the resistance after securing the + and - ends. Pulse fire on the Provari.
Despite this, I still get occassional changes in resistance of the coil. I always check the thumb screw, as it has a tendency to loosen. Slightly adjusting the wick-coil combo often helps as does doing a dry burn of the coil.

Bad, as rule said, a resistance drop=wick problem. The provari won't throw an error unless the amp limit is passed... there are shorts that the pro don't care about (ie you will get an ohm reading above .8ohm).
If you can, use a mech for the pulse method and if you're already at it, don't pre-oxidize at all. my
