Rebuilding

[ray72484]

I have an igo-W4 and was attempting to rebuild the coils today. I do not have an ohm meter as I was trying to do it the same way they were already made being a 1.5ohm coil. Apparently something I did was wrong besides not having a ohm meter because the coils actually caught fire. This only happened when I put my new sony batteries in it. If I use the batteries that came with my ZMAX it won't do it. Will a ohm meter from Home Depot that has the black and red leads be okay to check it. I have the sony VTC 4 batteries. In what range should I try to make my coils.

By the way I am using 30 gauge kanthan and silica

Always. Always test your coils. If you are just starting rebuilding, I'd recommend aiming for 1.5 - 2.0 Ohms. It is also unclear what device you are firing these in. Be careful, a hard short can be very bad in a mech mod.

I don't own a Zmax, but it is my understanding it should be able to check your atomizer's resistance.

I am vaping on a M16 clone

And can I just use a electric meter with the black and red leads to test it

I'd use the Zmax. From the user manual:

5.Ds--Display change
In this mode the Zmax will read and display your atomizer/cartomizer ohms measurement,your battery voltage and your atomizer/cartomizer output voltage.
This feature is useful if you want to check what type of atomizer/cartomizer you have installed,and what atomizer/cartomizer output voltage is when the battery is working.

I tried that but if it reads to low than it won't read at all

Also, are you trying to build a dual coil? Given that you said you have an Igo-W4, I'm assuming yes. Make sure you understand how resistance works in parallel circuits.

If it says it is too low, then it is too low. Start by building a single coil, read up on some basic electronics - you really need to understand Ohm's law and how resistance works in series and parallel. If these things don't make sense, you aren't ready to start rebuilding yet.

I really like the experience from my dripper but my coils went bad. I was using it on my zmax and I liked it. I got the M16 because I was told it would be a better experience. I finally got one at 1.5 but it is a single coil. It is okay for now until I can figure out what I have to do

Something to understand about using a multimeter. The leads themselves will add to the resistance. If one is building a sub-ohm coil, this resistance from the leads can be as much as what you are trying to get on a coil. The multimeter's reading could read 0.5 Ohms, when measuring a dead short. Here is a quick tutorial about how to use a multimeter. Important bit:

To read low resistance accurately, some meters have a RELATIVE function. Short the tips of the probes by rubbing them together, and look at the reading. It will be between 0.1 and 0.5 ohm depending on your probes. Now press the RELATIVE button. The reading will go to zero. Now when you read the circuit, the reading will represent only the resistance at the probe tips. The probe wire resistance has been zeroed out.

Based on your comments, I would seriously urge you to not try to build a sub-ohm coil. (You may not be doing this, but if you are, please stop and learn some basics first.) It is okay if this is all new to you, there is all sorts of stuff I am woefully ignorant about! Just take some time to educate yourself and learn to be safe.

Glad you got things worked out. Nothing wrong with a single coil. Read up on resistance in parallel circuits, that should help you. And above all, vape safe friend!

What would I gain out of going lower ohms over a 1.5 ohm coil

To answer your question; Yes, you can use the meter from Home Depot to check your coils. Don't touch the leads with your fingers though, it will throw the reading off.

Remember, parallel resistance of like values will devide the total by the number of coils so...

2 - 1.5 ohm coils will be around .75 ohms
4 - 1.5 ohm coils will be around .375 ohms

The actual formula is:
Rt = (R1 x R2) / (R1 + R2)

But as a rule of thumb when working with like values you divide by the number of coils...
