So I picked up an adapter 510->901 and gave it a shot. I can't get the darn thing to work! I get almost 0 vapor. I've tried a bunch of things, less juice, more juice. Nothing has helped. So I cleaned out and dried the atty, and if i turn it on, I can see the coils glowing, just barely past the bridge. Thing is, it takes a good 3-5 seconds for them to really get orange. My 401 does that in less than one if it's dry. So I hooked the thing up to my multimeter and it's ~3.3Ω through the atty. My 401 is about 2.3Ω. Is this normal? I'm just trying to figure out what the problem is, because one in a blue moon, the stars align and it gets hot enough and the flavor and vapor production is very nice. Any ideas would help! Thanks.
