Smok Fury-S Mechanical Mod not firing...

    Just bought this bad boy yesterday, along with a Kennedy RDA, and some twist .36 ohm coils.

    I built the RDA (just one coil for now) and stuck it on my normal mod (a Jaybo RX200s) and it fired straight away @ 3.7v (around 50w) perfectly without problems. I got really nice vapor production and flavor.

    I put the RDA on the Fury-S, a charged battery, stick the 7a magnet in, and cap back on. Press fire button, I hear a very faint sizzle for half a second, a tiny bit amount of vapor flows up, but then it stops "firing". Okay. Try another battery? Nope. Same thing. Hmm. Google a few things. Try cleaning the contacts, I check for signs of overheating, nothing. Last thing I can do is try the magnet without the fuse in it but I am scared it may blow up? Am I doing something wrong or should I try it without the fuse magnet?

    Not sure what this “7a magnet” is, but if that’s a fuse rated at 7amps, your build has exceeded that and has blown it.

    Got a multimeter? Check to see if you have power (by checking voltage) at the mods 510 when the power switch is pressed. If you do, your atty isn’t making contact with the mods 510. If not, the problem is in the switch or the battery/510 connection.

    Specifically, what batteries (make and model) are you using?

    That's a lot of metal for a single battery to fire up. What gauge is it? Did you check the resistance with an Ohm reader, multimeter, or regulated mod?

    Hi there! I do not have a multimeter, but I did check with my regulated mod. It was supposedly a .34 ohm coil, but my mod reads it at 0.24 ohms. No problems using this RDA with the same setup on my regulated mod @ 50-65w. I bought the coils pre-made at my local store.

    It is indeed a magnet with a fuse.

    Then you have blown that fuse, hence why it worked and now doesn’t.

    This is why its important to always measure each individual coil before using it, and not take the manufacturer's or vendor's word that it is a specific resistance.

    You still didn't answer my question what batteries that you are using specifically (make and model).

    If you indeed have a fuse in your mech, then if you must find out at what resistance or amp load that fuse will blow. You may not be able to use a super sub-ohm coil in your mech. Remember, a fuse is a safety feature that attempts to keep you safe. Don't bypass it, as that could be extremely dangerous in a mech.

    4.2 / .36 = 11.67, so yes, it looks like you've exceeded the 7A limit of the fused magnet.

    4.2 / .24 = 17.5 so if you've got a battery rated 20A or greater you should be okay using the other one [without the fuse] if that is the true reading of your coil.

    I'm curious. You say "a little bit of vapor comes out, then it stops firing." I presume that's the fuse tripping. Then you say "the same thing" happens on a different battery. Including the "fires for half a second" part, or just the "nothing"? I'm wondering because I have the same mod, wondering if it's a one-shot fuse or if it's some sort of "resettable" deal that will continue to work again once the current drops below the 7A limit. Can't seem to find much info online about it. Not quite ready to sacrifice the only one I have just to find out if it's reusable, but if yours is already tripped...?
