answers are not specific to product but generally for all rba/rda/coils should not glow or light up..they will only light up if the juice is not going to the wick,or pretty much dried up.well 2nd queston is connected with 1st.. airholes,will be your preference,,,usually though larger airholes would mean huge vapors,but a bit of sacrifice on flavor...i had mine drilled 3mm,no afc thou so when i want a smaller airhole i just put tape on it...on the vamo,well,i don't really put my meter out unless i don't have the vamo,i basically use it from batt check to ohm checks...9.9 error usually mean you are have a short on the coils,either the coil is touching the base or oner of your coils is touching the post.what kind of coil are you running spaced out?if yes try poking them a bit,they should not glow evenly,and also the wire might be wrapped too tight on the wick not allowing the juice to flow..
Thank you Zeus for the help. I just checked my coils again and the bottom coil had a hotspot. I fixed it, but the Vamo still gives me an error. But I can use it on my plain 3.7 mod I made. The factory hole is 1.5mm. I will probably use a small drill and make it a little bigger. I'm not sure what kind of coil I'm using because it came with the RBA and they didn't say.I "think" I might have it now and just need to drill the hole bigger. I'm going to do that and let you know how it comes out.Again, thanks. I appreciate it.
yup drill the holes out and if possible align it to be directly infront of your coil to increase vapor even more.as for the coils,well,those are probably stock made ones,just try tightening the post a bit see if that helps.as for the vamo error.have you used it with any other atty?just to rule out that its not broken..also check the positive post as well,vamo has a known issue that the positive post sinks and does not connect properly...thou mine does not have these if its bigger that what you have wanted,a small tape should do the trick or putting your finger there let k=me know how it turns out i will help as much as i can.
I just re-wired another coil using the "nail wrap" technique you talked about. It was still tough but I have it working now with no hotspots. It will have to break in a little more, but for now it's doing good. However, it's not really doing any better than before. I think that I just got too cheap of a RBA. Should have got something like the AGA-T2 or something.
do not worry mate,no rba is too cheap,my igo-l is cheap even cheaper is a china era,both of which can out perform any high end rba,and given day.what gauge of wire are you using?what ohm reading does it read now.now,if you have no hotspots,that sounds great,now air flow,,,to maximize vapor...try aligning the airhlole to the coil,,you should see the coil on the airhole itself.do not cover it up yet.a photo would help a lot, try microcoils...way way easier than spaced out coils...
do this,,,if you have a torch torch the wire until it glows,careful not to torch yourself.this removes some springiness.now on the the nail leave like half an inch or so,or just enough for you to hold the wire and the nail together..wrap the wire around the nail as tight as you can..as to the numbe rof loops,if its thin wire see if you can do 7 loops or to whatever the wire can,then mount to the rba/rdaremove nail dry fire until it glows,then pinch with pliers so they compress some more.when compressing,the mod should be off,or not firing..then insert wick...see if that works...
wait...you have something there no more hotspots right?what device are you using?can the vamo read it out?what ohms?ideally your coils should be like this///////close to each other right?now less vapor?hmm...how about taste? and th?airhole is it aligned?can i see a pic?pretty please?
Extra info: I use an iClear on my Vamo. The heads on the iClear are 2.2 ohms and I run it at 4.2 volts. So far, it has been out performing the RBA with vapor and TH. Here's a long awaited picture
My two cents worth:From the photo, at least it looks like....The coil windings are touching the positive center post (A short or short of some of the windings) This will give you a low resistance coil reading, the coils that aren't touching will be very hot.The coil windings are too loosely wound. You will get poor to no vapor.As a beginner, you should carbonize the mesh before wrapping the coil to insulate it from a short. When you progress to extraordinaire coil builder you can fore-go the carbonizing. Lately I have brushed my rolled up mesh tube against some cotton and form a very thin layer of cotton around the SS wick before wrapping the coil around it.The coil wraps should be snug around the SS mesh but not so tight as to make it short. It's all practice, trial and error. Did you see the ZEN video I posted about "Adjusting Coil for Even Glow" ?
