Help with ohms, volts, etc. What am I doing wrong?

[Bubba]

Hey guys and gals I could use some advice. Here's whats going on:

Been fooling around with different resistance stuff. From carto tanks to BCC to you name it.

I wasn't getting much life out of my cartos in my tanks so kept switching the resistance. Finally got sick of that and started using my BCC mega from VapeOnly.

So after doing some research, found a couple of charts with suggested volts for given resistance. Seems like I had the voltage set way too high, which would explain why I was only getting a day or so out of the carto tanks, and why the juice turned dark.

So I'm using the BCC's with reduced voltage and all was well.

Then I noticed that the resistance was creeping up little by little. I have my Evic set up to show the ohms. BCC started at 2.2, then 2.5, and so on. Finally got up to 4.0 before the evic just defaulted to "no atomizer found"

So, I'm thinking it's an evic problem so I test the resistance on another device, where it reads 9.9 ohms. This leads me to believe its not the device, but something with my vape settings.

Now I'm wondering:

Is this just how these replacement heads die, by gradually increasing in resistance until failure?

Could it be because of the juice I'm using gunking up the atomizer?

Would voltage set too low be as bad as too high?

Does the eVic have different settings for average and RMS voltage?

Here's the setup:

Evic
Bcc Mega
2.2 ohms
3.5 volts
50/50, 24 mg juice

Should also mention that it's not exclusive to the eVic, have noticed this same behavior on other mods as well, although eVic is primary

Thanks!

Could be poor connection.
9.9 is the same as no atomizer found. If you have a multimeter you can read the coil to see if it is actually dead.
Normally if I get a no read condition, even on an ego battery, I check to be sure the tanks center pin hasn't been pushed up. If it does not make contact, nothing will happen.

I'm thinking it was something with the replaceable head in the BCC. Swapped it out (didn't fool with anything else), Evic and LT both read it @ 1.8 which is what it's marked. I'm keeping a spreadsheet to be able to track it this time to get a better idea of when/how/what is going on.

Also, don't have a multimeter. Well actually I do, but one of my in laws has it. So I own one, just don't possess one

What they said, I normally see fresh rebuilds or newly replaced heads drop a little resistance (.1-.3 ohm) but never seen it go higher, you probably had a bad head or something along the lines of that. I wouldnt worry too much about a chart that shows what Voltage or Wattage you should be at, some juices I have dont like anything over 6-7w, but others dont really come out until I hit like 9-11w. I would adjust by flavor more than what a chart tells me.

Did you try taking the Mega apart and cleaning it out. Whenever I open it to put more juice in I always take the head out and clean the contact end off. As well as blow it out and clean the inner part of the base where the head sits. There's inevitably juice all in there which I suppose could cause problems.

Set your Evic on VW and forget about resistance.

Just to update, I swapped heads last night and so far so good. Multiple devices reading correct resistance. Could have just been a bad head, time will tell. I'll let you guys know in a few days...
