Rebuilding kanger head......

[Rangertrix]

Ok......so I have an MT3S, an old EGO- T 900maH and a Smoktech Winder 1300Mah. After numerous fillings and dry burns my silica wicks fell apart. I had read about rewicking with cotton and tried it. Worked great. Then my last head died. I had 2.2 ohm heads. I wanted a lower resistance anyway and didn't have anything else so I unwrapped one wrap and put the coil back in. Apparently it had grown in resistance from use and it still read 2.1 ohms on multimeter, so I used it. Again, worked great. I had read about micro coils so I decided to try it. I know it really isn't for use on EGO type batteries, but I decided to try. After some research, I made a 12 wrap micro out of 30 gauge kanthal on a 1/16 bit. Tested it and installed it. I tried to fire it with my old EGO-T battery and wouldn't fire. Just got the three light blink. Checked it, no visible reason for a short. I tried firing it with my Winder, and it worked great. Smelled something like burning rubber shortly after. Pulled it apart and grommet had black mark, but not burned. Soaked grommet in alcohol, and built new coils. No coil I built, micro or standard ever fired on the standard EGO battery, regardless of the resistance. All fired on winder. I put stock coil back in (the one minus a wrap) and it fired on both. I searched and someone said a stock kanger coil is 1/16 diameter, 6 wraps of 30 gauge. I tried that to no avail. My questions are: how can a stock coil be 2.2 ohms like that if I needed 11 or 12 wraps to hit 2 ohms on a micro? Does the burnt rubber taste of grommet ever go away ( it seems to be diminishing a little, but I taste it every now and again )? What is the wire size of a stock kanger head? I know my EGO-T battery is old, but it always fired the 1.5 ohm Boge carts I tried. I always assumed it was a short, but everything works fine with anything except the coils I make from the 30 gauge I bought. Same grommet, same everything. Battery doesn't know which wire is installed, what could it be? Did some searching and found a similar question, but the guy was not open minded and wanted to blame the vendor that sold him the wire so didn't get any answers.
Thanks.

Update: apparently the grommet is some kind of silicone so the burnt taste appears to have gone away after a mL or two. I am wondering if the original head was actually 32 gauge and the 30 gauge drew enough current to fool the old JoyeTech EGO battery into detecting a short? The benefits of a micro coil I read about seemed seemed beneficial, but may just simply be beyond the capabilities of EGO style batteries. Probably safer that way, lol. I think for my EGO style batteries I would be better off simply rebuilding them back to original spec. If someone could tell me the spec' s of the stock heads it would be greatly appreciated. I'm shooting for a 2 ohm coil and I'm thinking probably 32 gauge 1/16 diameter with about six to seven wraps?
Thanks.

It may not be any help but I wrap my protank coils on a 1.5mm allen key with 32 kanthal and with 6 wraps I get 2.0 ohms. IMO ego batteries don't have the knards to fire microcoils properly, nor do 14500 batteries. The burnt insulator could be from the coil being too low in the head or just a bad build. When I fire up the coil for the first time to check I look to see if if the coil legs are getting red along with the coil. The coil should get red from the middle to the outside but not go down the legs if so then the build is trashed and a make a new one. There are a few variables to why the legs get hot enough to burn the insulator..hotspot in the coil..coil too low...one of the legs is kinked and/or bent and too close to the edge. Try not to twist the wire while making the coil. I watch videos of people wrapping coils just haphazzardly with little to no care and you could end up with problems. Any sorta kink or bend in the wire IMO has adverse affects on the end product.
As for what wire is used in stock PT coils I have no idea but I do know that the wire and wick is crap thus so many having problems with kanger heads.
I did the microcoil thing and they are nice but super juice hogs along with trying to dryburn them to have all kinds of ohm readings in the end of the burn. I think that you don't scrape all the carbon chunkies out of the inside of the coil it changes the ohm readings, so I reverted back to just wraping regular spaced wraps and vaping happy.

Ok, yet another update. I bought some 32 gauge wrapped a coil, tested it and it fired on the standard EGO battery. I used it on my Winder and went through a tank of liquid. No issues. I went to charge my Winder and use the EGO battery and it wouldn't fire. Went to refill tank and figured as long as I had it apart I would try another coil. It fires a couple of times on the EGO then it just goes back to blinking three times when I attempt to fire it, but works just fine on my Winder. Completely lost about this.

I can't help since I gave up the ego's loooong time ago just because they are so finiky and a PITA.
This might help with some ECF and other threads to what the problem might be.

Try pulling out the center pin on the EGO battery, it may be pushed down enough to make an intermittent contact with certain attachments.
