keep popping my coil on genesis build (youde agi) and getting much less ohms than what's initially read

[spacenoodle]

hey guys!

so i decided to give my agi's genesis option a try. after building it using riptrippers "genesis atomizer coil wrapping for a newbie" youtube video as a reference, prior to firing it i'd check the ohms and it came out to 0.4. pulsing it to get rid of hot spots (a MUST) i broke my 28ga kanthal 4 times in a row. i tried higher ohms the second time reading 0.6 and it didn't pop. anyway, after adding liquid, it performed well but ended up reading 0.9 ohms. i tried it again and got back to my original 0.4 ohms without popping the coil, but after adding liquid it went up to 0.7ohms. i was aiming for 0.5-0.6. any suggestions or feedback?

You'll probably have a better response in a different part of the forum.

Try that initial pulsing using an almost exhausted battery, 3.7v or under, better an old ego one if available. Good luck!

Something sounds off. Here are a few things to check.

- As mentioned above, you can do your initial burn-in using a partially charged battery. On a fresh battery, you are looking at about 4.2-4.3 volts. At 4.2V and .4ohms, you are pushing 44 Watts/10.5 Amps. This is safe on an 18650 AW IMR (1100 or 2000 mah), but above the safe limit on an 18350. Do your math to be sure you are not pushing your batteries too hard. You shouldn't be popping 28g coils at .4ohms unless you are firing it for too long as far as I can figure.

- The fact that your resistance changed that much between a dry and wet coil doesn't seem right. I sometime can see a 0.02-0.06 change in my setups, which doesn't surprise me, but a .2-.3 difference indicates something else is off. I suspect you are shorting out somewhere.

- What are you using for your wick? Are you doing a SS wick? If so, is your wick hole into the tank insulated? If not, did you oxidize the wick correctly before installation?

If I were to try and make a guess based on the information I have I would say that you are doing an SS wick on a genesis atty without an insulated wick hole. You didn't get a complete oxidation of the wick which is leading to a short under load which is aggravated by the juice being a conductor. I would make sure your wick is correctly set up. I understand that SS can be challenging although I have never wicked with it.

You may also be wrapping too tight. You want those coils as loose as possible, while still touching the wick all the way around.

The AGI has a poor quality center post, partially made of a spring, its almost impossible to build without hours of hotspot checks. Throw it away and buy any other UD genny.

I agree with yotogi, sounds like you are shorting out. If you are using SS mesh or rope for a wick, make sure it's not touching the bottom of the tank.
