I have built a couple of coils for my lemo at different resistance gauge of wire ect. But none of them with fire for me. I really cannot figure out if im doing something wrong or what. The coil that came with the lemo 2 worked flawlessly. Can anyone help me figure out the issue
Lemo 2 coil issues PLEASE HELP!!

I don't have a lemo, the only issue I had with my coil not firing is because I had built it too low and the istick said " no atomizer" oh I also tried once to get a duel coil to fire and it wouldn't because a little wire was touching the deck ( I had to see it through magnifying glass to realize wire was crossed ) don't know if this helps any but I imagine someone much more savvy than I will give you some thoughts
I think we need more information to figure this out. What type of battery are you using? And what is the resistance of the coils you built?
The battery i am using is an efest 20A 3100mah, resistances i tried were 0.8, 1 and 1.6ohm. I used 28g and either 24 or 26g unkown came with the lemo. Wrapped them around a 2mm rod cant remember the number of wraps sorry. All of the resistance above was done with both gauges of wire. And I using it on a kbox.

There's the right of it. I have a Lemo2, and I know what it came with from the factory (.55 Ohm Kanthal contact coil, I didn't measure but prob 24 or 26 ga wire, 3mm-ish mandrel) But we need to know what resistance coils you built-- preferably resistance, wire type, gague, wraps and mandrel size, but the resistance measurement alone will be a big help-- and what kind of mod you're trying to fire it on to help you.
I thought i might have had that problem too but there was no indication of a problem on my kbox. Usually if theres something wrong the lights go crazy. I also checked if there were any wires touching the deck but it looked okay. I tested the connection by using a straight piece of kanthal screwed into the post with no chance of contact with the deck and no luck with that either.
Ok, that's good. What mod is your Efest battery in? Some won't read below 1 ohm, but the 1.6 Ohm coils probably should have worked, even if the 1 Ohm might have been too close to the line. Hhhmmm... the Lemo has 4 screws, despite being intended for single coil builds, to aid in coil placement. Are you sure you don't have both coil legs attached to one side of the battery?
I don't have a Kbox, but I looked it up. It's supposed to have a "coil capacity indicator" a series of LEDs indicating permissable wattage settings. Are you getting anything on that?
Huh. By me, then. If the mod still works with your Nautilus, all I can suggest is build some more coils and try again.
First thing, do you have a multimeter or another mod to test it on?
Second, check your coil legs to insure they haven't broken when tightening the screws.
Third, are you using flattop or button top batteries?
There is a known issue with the KBox having issues making a good connection with flattop batteries (with it firing ok with a different atty, I assume this isn't it; but worth a try).

The only time I've had my Lemo not fire was when the positive 510 connection on the tank wasn't contacting the 510 positive on the mod. The pos on the Lemo is flush with the neg ring or even recessed sometimes. That gives a problem with some mods. But since your Kbox lit up it sounds like it was actually detecting the coil. I don't have a Kbox, I looked it up and if it detected an out of range coil or a short or a low battery it would have flashed 3 times and turned off. If it didn't detect a coil it wouldn't light up at all. It can't be a bad battery or it wouldn't fire other tanks. Those resistances are well within the range.
Only other thing I can think of is I've heard of Lemos doing odd things if the screw that holds the build deck together is loose. Guess it could have come loose when you were doing the new coils.
Did you try dry burning it, or just do it with the tank assembled and juiced up? Easier to see what's happening with the coil exposed.
But the fact that the Kbox acts like it has detected a good coil has me baffled. Wish I could be more help.

I guess if something went wrong and the coil ended up with really high resistance, the mod might think there was a good coil there but not have enough power to heat it up. That could happen if the wire broke when you tightened up the screw, like Rangertrix suggested. Hard to imagine it happening the same way on multiple coils though.
rangertrix unfortunately i do not have a multimeter and its a button top. I was also just fiddling with it now and tested how tight i have to go to break the leads and i dont think that happened for my previous coils. I also just noticed something, when i put the lemo deck on my ohm meter with any coil it goes crazy. It starts with zero load then 14ohm then 10 then slowly its comes down.Sometimes even higher. However when i put my nautilus on it showed 1.7ohms straight away. Is that normal?
I've had the same thing happen with the Lemo on an ohm meter. I tracked that down to the Lemo 510 problem I mentioned previously, where the positive pin is recessed into the negative ring. I put an adapter on the ohm meter and it worked fine. Try moving the Lemo 510 pin out a bit and see if it works on the ohm meter then. If it does then that might also be the reason it doesn't work on the mod.
So i did this and it worked!!!!! The issue with the ohm is gone too.
One new problem has occurred though, with the positive pin being loosened the positive connector on the deck is wobbly which causes shorts. I tried to fix it by putting a spare rubber O-ring on the positive pin that screws the positive part of the deck down. So far it seems to be okay. I am just wondering if this fix is a good and safe way or is there something else i should do.
I just read back through this thread and realized you have a Lemo 2. Mine is the original Lemo. Still I assume this part of it works the same.
OK. There are 2 screws involved here. The first screw is the one that attaches to the positive part of the deck. That screw should always be in tight. If that's the screw you put the o-ring under you should take it off. As long as that screw is tightened up the positive on the deck won't be able to move.
Then look at the bottom section of the tank, the part that screws into the mod. There should be a screw on the bottom of that. That screws into a dome shaped piece on the inside. When the bottom section is attached to the tank that dome shaped piece will be in contact with the end of the screw that goes up to the positive on the deck. The screw you should be loosening is the one on the bottom. You might have to hold the dome shaped piece while you loosen the screw. Just back the screw out a couple of turns. It will be loose at that point and the dome shaped piece will be loose as well. But when you put the bottom section back on the tank that should push the dome shaped piece firmly down.
On mine the screw on the bottom will be loose at this point, and it should be extending slightly from the negative ring. You can put an o-ring under this screw to keep it stable but it isn't completely necessary. It needs a really small o-ring. The ones from the small screwdrivers you get with some tanks are perfect. Or you can cut a small piece from a larger o-ring with a razor knife.
Again mine is an original Lemo and it might be different from yours so I apologise if I'm misleading you. But it seems like you're making progress anyway. Let us know how it goes.
There is no screw on the very bottom of a Lemo2. It's a pin.
Make sure the internal screw that attaches to the center post is tight and then screw the bottom section on good and tight...firmly attach to your mod and you should be fine.

I had to loosen that internal screw for it to work. By the looks of it the internal screw and the pin arent making proper connection. I put an o-ring around it so the deck would stop shorting.
