Can't get my coils to fire, what am I doing wrong?

[dj9928]

I'm at the end of my tether trying to rebuild my Vivi Nova heads, I have done upwards of 15 attempts, 3 fired but crappy throat hit and minimal vapour, the rest never fired at all, where the hell am I going wrong? Yes I know I should use a multimeter but I don't have 1 and now I have no heads and damn all to vape

I used 2mm wick and .2 kanthal wire, I followed a Youtube turtorial but here is what I am doing, I use a pin hold the wick and pin in 1 hand, wrap the wire around 4-5 times, Put it in the head, space out the coils so they aren't touching, pull all through and remove the pin, put the little rubber bung over 1 wire and push it in, put the other little metal bit on, trim of the access wire.

Long story short damn all happens when connected to either my ego or ego twist. Some coils I can get to fire but as I say they are not working correctly. HELP

No ohm meter = no luck.

Go to the auto parts store and buy a $10 multimeter.

Your e-go protection circuit is stopping the coils from firing

I am of course guessing, because you have no meter.

Yep, gotta be able to check that stuff before even trying to fire the coil. If you don't know your ohms, or if its shorted out and you don't know, you can get yourself into some trouble.

I think it'll be easier just to buy some new heads.

That's up to you.
But if you do decide to continue rebuilding you will need a multimeter or ohms reader. It's a small price to pay to know your coils will fire and fire safely with your setup

Your ohms are probably too low to fire. Or too high to fire. Either way you need a multimeter or a device that can measure resistance such as a provari or an mvp

What gauge kanthal are you using. Is it 28 or 32? I'm not sure what 0.2 is. Also make sure your head is making contact with the top of your battery. Sometimes the top of the battery gets pushed down and needs pried up a little. Otherwise are you sure you don't have a wire touching the wall and shorting out..oh and get one of those ohms readers..lol

It's a good idea to have a DMM just to check new heads to make sure you've got a good one. They can be bad too, and sometimes meter all over the place. When I order cartos, atties, heads, I check em all when I get them. When I pull one out of the drawer, I meter it again. I like knowing what it is before I push that button.


Getting one of these meters is one of the better investments you can make.

First off you MUST have a way to check the ohms be it a device that can read it, a multimenter or a dedicated ohms meter. It is FAR to dangerous to be rebuilding without being able to check.

On the heads, some ideas
- are the legs crossed/touching inside the head
-are the coil loops touching the side of the head body?
-add an additional wrap to increase the ohms
- are your wraps so tight on the wick that they are choking off the juice flow?
- has your coil been pulled down into the heads body? you want it sort of even with the cutouts on the sides not down inside.

No idea what wire you are using. If you are doing just a normal sort of wrap setup 32 gauge Kanthal is good. If you are micro coiling then go with 30 on a protank head.

What I do with a normal wrap setup is unbend a large paperclip and hold that with the wick. Then I wrap around the wick AND the paperclip. I leave the paperclip in until AFTER I have locked down the legs. This keeps me from pulling the coil too low in the atty and keeps me from wrapping too tight. Then just slip the paperclip out.

Right guys I have had a break through, well sort off that leads to a different issue, after going through almost 1m of kanthal wire making coils with no results I remembered I had an old vision CE5, Essentially the same thing as a Vivi Nova but different centre post, put one of these non firing coils on it and hey presto we have take off. Tried another it fired, and another it fired, I have a little voltage thing taken of a machine I own the readings aren't accurate as such but the little dots illuminate anywhere between 1.5 - 3.2 depending on the number of coils I have.

I put them back on the Vivi nova and still nothing is happening, I inspected the centre post, pushed the little bar etc nothing is happening. The difference between the CE5 and the Vivi Nova centre post is the CE5 seems to be spring loaded where as the Vivi Nova is not, Is my Vivi Nova fooked or what's wrong? The CE5 is OK but the Vivi Nova holds twice as much juice.
