SGv3 - Troubleshooting Wick and Mesh

[Krythis]

I've seen some side conversations in each of the 'Gen' threads, but not one particular thread for the wick and mesh issues.

I have a SGv3 and when I bend the mesh the top arch is somewhat oval shaped. This has been giving me a hard time with both shorts and the wire being too far off the wick on points in the coil. I started adjusting how I roll the wick to prevent this as much as possible, but I'm still getting small sections of the coil that have intermittent glowing issues.

I've tried burning more juice before making the coil and that hasn't helped much. When I probe with a multimeter I can see there is a short in the coil each time, but it's difficult to get the coil loose enough to where there's no short while being close enough not to glow. Does anyone have any tips & tricks or person success stories that may give me some ideas on how to narrow down this issue?

Can you post some close up pictures of the wick and coil?

I think the issue I'm having now is wicking.

Your mesh doesn't look like it's oxidized very well to me, mine is pretty blackened. A three wrap coil has to be a low resistance so I wonder what voltage you're using. The coil might be to hot for the wicking rate. As far as wicking goes I had to develop a tilt method to keep the wick wet. I may be wrong but something to think about.

1.6 ohm at 3.5v

Wick was cleaned up a bit fiddling with the coil the past 2 days.

Tipping has helped, but prior wicks have wicked much better. I also went down the 15% vg

I'm using 60/40 Pg/Vg and 2.5ohms @ 4.5v. I should mention that I've changed the stock configuration to a "J" wick and re-did the connector by soldering the positive wire to the inside of the ce2 tube to stop the leaking. The air flow comes from a hole in the top cap.

HELLO ALL

Just got this v3. And instructed I fired and blew approx 1 tank of pg/gf mix then filled with 50/50 pg vg the filed with vg pg red bull and vaped. All was well. Using usb at 4.8 4.9v metered . The element is 2.9ohm. I am now on tank 3 and vapor is dropped. Firing time has increased to 5-6 sec before vapor begins . Then almost immediately it gets a burnt flavor... Acrid taste. Here are pie of wick

Dryburn to clean the coil and wick, that black crud tastes terrible and prevents the wick from wetting the coil.

After you dry burn to clean the coil and wick you can rinse it out with hot water.

You may want to change out the juice too, as I've heard that it can get tainted from the "black crud" and would still taste bad after cleaning the wick and coil.

Try pulling the wick up a little bit, it looks like it is pushed down too far.

I'm curious why the air hole is blocked off, wouldn't that negatively impact the wicking?

The small hole that is plugged on top is the fill hole for the juice. I believe that it can be plugged and it should still wick fine.

The first vid is a VERY LONG drag, with little results, The second is a cap off, lonf fireing that lasts until the http://www.youtube.com/watch?v=g7QywKMtsPoT cuts off automatically.

As suggested I pulled the wick up a little dry burned and brushed the "crud" from between the coils and then rinsed under hot water, then refilled and that is where the videos pick up/

Still seems very poor. I have seen other vids or vapor production that exceed even a dual coil.

PS. I metered again the coil and PT, they are 2.8ohm, and 3.7v

 

[Robert T]

The last time I checked my coil was 2.5 and my voltage is set at 4.5. It appears to me your not giving it enough power. If you can't change the voltage then change the resistance of your coil,make it lower. Maybe 1.5-1.8 ohms.

2.8ohms at 3.7v is 4.8 watts, that will not make much vaper, IMO for real vapor you need between 8 and 12 watts, you need either more volts or less ohms...

 

[Robert T]

That's what I said lol

I tried my other PT, it is metering at 4.9v It isn't much better. 8.5 watts

After you dryburned was the whole coil glowing red? I would just wrap a new coil.

 

[Youssefa]

UPDATE.....

I am at just over half a tank. I am a heavy vaper. I have observed that when holding the unit perpendicular or just a bit higher higher than my mouth it wicks really well, flavor is almost too much, vapor is good. But when i hold it down (like drinking from a straw) after a couple of2-3 drags it's done and I have to lay it down. Also when holding perp to my mouth I end up with juice in the top cap. the fill hole is plugged.

LOL. I can't figure out how to turn the nut to loosen in order to put new wire on... I was going to wrap it with 2-3 turns instead of 5.

You guys are way ahead of me, i am kinda lost with my Sv2; new to computer so do not know how to take pics either,lol! Maybe i will keep on this thread, the other ones are so long i get bogged. Thanks for the posts!
