Rebuilding heads that go beserk

[Susaz]

Yesterday I rebuilt several heads, a vapeonly, a couple of evods, and a Protank head. All with the same method: 32 ga Kanthal, 5 turns, on 2 mm silica, one of the leads to the side, the other one through the insulator and through the center pin. As I was putting center posts, all read the same with my evic: 1.6 to 1.9 ohms. I put them away and when I used them today, the vapeonly was reading 0,6 (low ohms). I watched every video available, and I'm quite handy at building my Terminator Cs. So I really can't figure out what's wrong. Any ideas?

feel around the base and see if maybe you didn't get a wire clipped close enough. Also look down the tube and make sure the coil is centered so it isn't touching the tube itself.

You said through the center pin. That second wire should be pinned up against the rubber by that little metal plug piece not through the hole of that metal plug.

I apologize if I misunderstood you

You didn't, I made the mistake. Maybe the leads are too long, I'm clipping them with a huge clipper. Thanks!

I don't even clip them anymore I just sort of bend them around in circles until the repeated bending right at the edge of where wire meets atty breaks them off flush.

Nail clippers work very well for me. I have a tiny pair for clipping babies nails and they work better than a regular sized clipper cause they have a big fat plastic handle for my fat fingers.

This is generally the issue I run into when I rebuild eVod and ProTank coils. And it causes my coils to read <1.0 ohms. A simple fix that usually works is to take something sturdy but thin enough to fit down there (like a thin nail), and push both ends of the coil towards the center.

I use tweezers for that

I have a tiny flat screwdriver for that! Thanks everyone!!!

Is it also critical that the coil wraps aren't touching each other?

I haven't attempted any rebuilds yet, just trying to gather information for future reference.

From what I understand they should not be touching each other but then I have seen videos where they obviously ARE touching and nothing is said. So I just follow my gut and make sure they are NOT touching. I figure it is safer that way.

if you oxidize your wire well, it won't cause any issues if the coils touch each other. if not, you've created a short and your resistance will drop.

yes, it is safer to make sure they do not touch - no reason to take the chance that your wire isn't fully oxidized.
