When the reading changes is it time to change?

[Papillon61]

My Kanger Geni is loaded with a 1.8 ohm coil. So far my mvp has always given me a correct reading ranging between 1.7 to 1.9 ohm. This morning however I'm getting a reading of 2.7 ohm on that particular atty. The others read correctly at 1.8. So is it time to change the coil, clean it, dry burn it or what?

Quite an extreme jump all at once. My Aspire mini will jump a tenth or two, of which sometimes by cleaning the contacts to the battery will drop it back down. If your atty is tight to the battery, contacts clean, and flavor is still there, I would say keep using it. This opinion is coming from someone who has not had good success with coil cleaning. Dry burns? May fry your cotton wick, then you can trash it for sure.

 

[Papillon61]

Yes everything seems to be clean and I get the same reading when I run the atty on other gear is well... so it can't be the contacts on that particular battery. The vaping is not satisfactory no, kind of weak is if the coil is taking it's blessed time to heat up by which time I'm over the limit of the puff time and the button starts flashing.

Throw spent coil out insert new coil. Prime it properly and vape.

Yep that's what I had to do. So now I know - if the atty gives that kind of reading the coil is bye bye.

Just a thought. I ran Genisis attys a lot a couple of years back. The only time they went up in resistance that much (other things being equal) was when I had a loose nut on the pos or neg connection. If you tried tightening the connections and that didn't help, ignore this. If you didn't, next time it happens try that.

I'm not very techy and a newbie in vaping but if you are talking about a RTA mine is not a rebuildable. I don;t have anything that can be tightened.

Just got back to your thread and found others had answered your question...trash the coil & start off fresh. This vaping thing isn't rocket science...when the flavor takes a bump...likely your coil has too.

Sometimes I am getting big jump in resistance when I use premade coils from Fasttech. They have welded legs and I believe that wire "thinning" occurs at welded point (thin wire = high resistance). If I use such coils longer they will burn out pretty soon. I do not like to vape on metal vapor of burnt out coil, so if I see jump in resistance I promptly change coil.

So that is 2 coils heads in just about as many weeks! This could become an expensive business. I've been looking around and watching videos and stuff.I don't thin I am expert enough to wind a coil as yet. So would something like this work in rebuilding my Kangertech aerotank dual coil heads? These are the new longer heads with the holes at the side. I've seen a video where this guy only put one coil in the head even though these are called dual coil. Is that correct? What I don't like about these pre-made coils are the materials used - Nichrome + Fiberglass. Please tell me what you think. Thanks.

Does not give the diameter of the wick for that one. Also nichrome and fiberglass?

Why I am moving up to a single bottom coil tank. Want to rebuild them and do not want to deal with dual coil rebuilds. And the short reported life of the premade dual coil heads....

 

[Papillon61]

Does not give the diameter of the wick for that one.

It does this on the page:

Wire features:
Nichrome resistance wire with welded non-resistance leads
Leads length: 30*30mm
Wire diameter: 0.2mm
Resistant: 1.7ohm

Wick features:
Material: Fiber glass
Diameter: 1.0mm
Length: 50mm (approx.)

I use Eco Wool in my Ithaka synthetic wick dose have its advantages way higher burn temperature over cotton. yes you can build your own coil and use a single where dual coil was. You can get several rebuilds out of a single disposable coil head.
You should get a cheap multi meter or a 510 OHM reader to check for shorts before you use it after rebuilding. Its really pretty easy with a little practice. Wire and wick materials are cheap when you buy 100ft of wire and if you re wick with cotton a life time supply of organic cotton pads is about 12$

This as well as the pin on the mvp can "sink" lower into the mod. Many threads on how to raise the pin back up...gently.

My bad. When I read 'Geni' I immediately thought 'Genisis' and I went with it
