Dual Coil not firing

[xDudex]

Hey all,

So I've been curious about dual coil builds. I've been using my Reo and Reomizer v2 for some time now and thought I'd venture out. Anyway, I got a Launcher V2 and a V5 dripping rba. So, I set it up using 28 ga, dual coil, coming out to .75 ohm. Tossed it on the launcher to test fire and... nothing. Using it in 18650 mode with a Trustfire battery. I believe it's 2000ma 3.7 (obviously). I'm not sure what I'm doing wrong. I was thinking that the base just isn't making contact with the launcher's pin, but I'm not sure if that's the case. I ended up tossing the atty on a zmax mini (stupid I know), and had to crank the volts to ~4.7 before the coils even started to vaguely glow red. So I don't think there's anything wrong with the atty.. it's obviously something I'm doing and I just don't know what. Any help is greatly greatly appreciated!

Can you not adjust your pin on mod? Ahs how did a z max fire a ~0.7 ohm coil?

If you have a multimeter handy, monitor the voltage on the terminals of the RBA while test firing.

The pin can screw out, but only screws in so far. I've tried and I don't want to tighten it any more and risk stripping threads. I'm not sure how the zmax was able to fire it (really weird). But, it read the coil at .6 :/. I'll bust out the multimeter and see what it reads. Otherwise, I guess I'm just gonna drop some dough on another dripper (albeit that's not what I want to do).

See what voltage the z max is putting out while you're at it.

The zmax will fire it for a quick burst if any longer you have a short and ohms are jumping around.

Will do, but first a question that might just answer this whole thing... lol. I just realized my 18650s have a PCB. Would this be the reason for all this?

If it was a mech yes, the zmax has protection out the wazoo. If I remember correctly ohm cutoff was 1.3? Been awhile since I had my zmax

 

[xDudex]

I'm using a mech mod. I was just using the zmax to see if it was the pin not making contact with the atty. I don't personally use a zmax. Took it from my bro for a minute haha. So, since I am using a mech, and the battery has a PCB on it, that's why it won't fire the subohm coil?

 

[Jjshbetz11]

Most likely, do you know the cutoff on the battery? My pcb 's are .6

 

[xDudex]

I was trying to research that and couldn't find an actual limit for the trustfire. What I did find was a volt cutoff limit (I believe) of 2.4v. I'm not sure how to calculate that to ohms though.

In a fit of frustration after getting home, I removed one of the coils. Came out to 1.5 ohm. Tossed it on the zmax, and it fired. So, then I tossed that on my mech with an 18350 that I knew was charged, and it wouldn't fire. So, I think the consensus is that the atty isn't making contact with the pin... which is really strange to me because I had a fogger on the mech that does fire and the threads seem to be the exact same length as on the dripper. I'm stumped. We'll see how it goes when the nimbus comes in... :/. I appreciate all the input though guys. Think we should just call this a case closed unless anyone has another idea.

If its a dripper, and only a two post the positive post can be wiggled down witch will drop down the positive pin on the 510 connection if that makes any sence..

That makes perfect sense. I'll try to fiddle with it some more today.
