Ohm Meter Reading 0.00?

[count chocula]

Hi all. I'm new to this forum. I've been vaping for a few months now, and decided to try a dual coil atomizer (I normally use an aspire clearomizer on a DNA20 mod). I bought an ithaka clone, and am having trouble getting it to fire on any setup I have. When I plug it into an ohm-meter, it says "0.00" with a single coil. Does this mean it's shorting out somewhere? I made this coil with some ready-made R-NR wire that I bought from stormy's. I've tried making multiple different coils and checked the connections several times. I can't find anywhere that it would obviously be shorting out... The ohm-meter works, as you can see from the third picture. Any help would definitely be appreciated.

Did you try putting it on your mod and checking the resistance? Perhaps there is no contact between the atomizer and the ohmmeter.

Either it's shorting out or the center pin isn't making contact. I would try putting it on the ohm checker with no coil and see what reading you get then.

Cheers,
Steve

Second the pin not connecting.

If R-NR means resistance, non-resistance wire, shouldn't it have no resistance?

You use that wire where you wrap your silica with the resistance part of the of the wire and the non resistant part is the legs so it doesn't heat up and burn (for example) the rubber insulator in a protank.

Thanks, for some reason I was thinking the coil was made entirely of non resistance wire.

You have a short; the leg of NR wire that is supposed to contact the center pin is touching on either the other leg of wire, or the outer body.

Wow. Thanks for the fast responses. You guys are great! I'll try to figure out where its shorting I guess. fyi when I plug in the ithaka without a coil it also says 0.00, or sometimes 0.03. The number also just jumps around alot depending on how much I fiddle with the atomizer. What is it supposed to say without a coil? zero?

 

[Wingsfan0310]

I would think without a coil, it would read non or infinite resistance. There should be no connection between positive and negative. Something doesn't sound right there. Unfortunately I don't have an Ithaka or I would be of more help.

Edit With a piece of non-resistant wire between the positive lead and negative, I would expect 0 or close to it (a direct short), with nothing it's an open circuit

take the topper off and check what it says without anything; probably will say 9.99

Looks like your ithaka itself has an internal short.

Its working! You guys were right, it was shorting where the positive pin meets the metal cup/ceramic cup assembly. That washer wasn't sitting in the hole properly and I think the positive pin was contacting the metal cup. Now it reads 2.62 ohms and it fired for the first time! I'm pretty excited about this. My wife is looking at me like im crazy. Its the little things... Thanks to everyone who commented.

Im glad you got it working I had to Fiddle with my Ithaka I just set it up for my first time ever I also had shorts doing a dual coil but watched JCwest's video & got it working! It is truly an awesome vape!

Glad you got it figured out, this is one of the more difficult rba's to build, and is prone for the center pin to short out when tightening the ceramic cup to the base. I got into the habit of testing the ohms without installing the O-ring first, that way if I needed to adjust it, it wouldn't mess up the center pin when taking it apart.
