"Low Resistance" and the Uwell Crown .25 dual coil

[StrahmNoMore]

So here's a new one, at least for me. Tonight I primed the heck out of a brand new .25 SS uwell Crown coil. Threw it on my sigelei. Gradually worked my way up the wattage, tootle puffing my way all the way up. Got it to 70 watts, had a few hits sat down for about 45 minutes and came back to it and it wouldn't fire. Just got the "Low Resistance" warning on the sigelei which was reading it as .1?? Took it off, cleaned the 510, put it back on, same thing. So I threw it on the ipv3li. Same thing. Finally, I just replaced the coil with a .5 and it's back on the Sigelei and seems to be working normally. Could someone tell me what might be going on though? Should I just toss the coil? What could have happened to it?

Seems pretty clear that something shorted, maybe the wire shifted a bit after getting heated up and is making contact with something it shouldn't in the housing. Whatever happened, a sudden drop in resistance that big (relatively) is a short.

Ok. Thank you! So it is the coil then. I'm glad it wasn't the mod! Got these coils on sale and still have a 4 pack of them so no huge loss.

Most likley a bad coil, I have yet to get one out of about 5-6 packs, but its not impossible. I would just try another coil and see if that solves the problem.

Sounds like it was. I've been vaping this .5 on the Sigelei for the last few hours since and not had a problem. Glad I didn't get the coil at my B&M they charge $7 a piece for those!
