ProTank 3 coil rebuild walkthrough.

Hey guys,

Just thought I'd post photos of my PT3 dual BCC rebuilding.

Sorry, but no webcam for video and it's rather hard to hold a cell phone while doing this task. Had to split into multiple posts due to # of images.


The coil removed from the PT3 and base.



Coil dissasembled- it comes apart like the other kanger coils.


Coiled the wicks, 2mm wick with 32ga kanthal- the helping hands thing really helps!


I did 8 winds for each coil. Since there are two coils, wired in parallel, you need to do two 4ohm coils (to acheive the stock 2ohm). I estimate mine should be just over 3ohms each to give me approx 1.5ohms total. This is a rather difficult procedure, the number of winds required mean you have to really get them in there tight so they don't short out on the housing, but not so tight the coils loops touch eachother.

Place the first coil in the housing.

Weird, it just won't let me upload some of the photos....

Anyway, next you install a blank spacer wick to keep the coils from shorting on each other.

Then you install the 2nd coil, paying attention to where your leads go - i make my coils with one leg longer than the other for easy reference.

Again, install a spacer wick- here I don't use a full wick, i pull a few fibers from the wick and place it on, just to ensure the cap doesn't short on the coil.

Install the cap and it should look like this


Insert the rubber plug with two of the wires (of the same lenght leg) through the center and the other two on the outside


Insert the post cap.


Trim the coil wires and wicks down and you should end up with this.


This coil reads about 1.6%

If you find you have some dry hits, try removing a few fibers from the middle separator coil, only a few at a time, until it flows nicely.

Weird, i think the forum is broke, pics are all whack.

I see them just fine on mobile.

Excellent work.

Very nice tutorial on building daul coils for the Protank 3.

I like not having to watch YouTube because my satellite provider throttles down my usage when I watch too many youtubes.
