All kanthal A1 ... tried 30g, 28g, 24g wire ... ohm it out on a smok ohm reader .... always get a solid ohm of .4 to .8 depending on the wire gauge used. I tap the goblin a few times while on the meter, to see if I get any fluctuations from bad connections & what not. I get a steady ohm reading each time.

But when I place the goblin on a mod & shoot some voltage to it, I get the same leg glowing bright & can't seem to get power to the rest of the coil or the opposite parallel coil. Both coils are identical. Both the same length, same legs, same wraps, same gauge.

Anyone know what to look for, as I think it's gotta be an atomizer issue.

Have you tried squeezing the coil? Brushing it with a screwdriver? Both of those usually help with hot legs. Could also just keep pulsing it to try and work out the hot leg.

If that still doesn't work, make sure the coil itself isn't touching anything. Where did you get your kanthal? Could be an issue with the wire you're using.

I always get a glowing leg when testing coils without a wetted wick installed. The end of the coil in free air has nothing to sink the heat to. The coils in the middle have enough integral mass to sink heat between each other and average it out as long as they have good contact with each other. All you can do is heat the coil to glowing and immediately pinch it with tweezers and hold for a few seconds to let it cool.

Before doing the tweezer thing, heat the coil to glowing several times to oxidize the wire. The oxidation process serves to insulate the coils and allow them to touch without shorting out.

Install a wick, wet it with juice, and try again. I think you will see that it doesn't glow unless you apply some insane voltage. I always do my testing at 4.5v or so.
