Possible Solution to 901 fitting to avoid battery destruction

[nicowolf]

I found this today. I was at Radio Shack looking for parts to attempt my own Magnum Mod. The guy there was really quite helpful. This part fits my 901 atomizer perfectly - sadly, I cannot figure out how to wire it up. Any help would be greatly appreciated.

Size N Coaxial DC Power Jack w/Switch - RadioShack.com

i'm curious about that. it says w/switch....
guessing the switch part means that it diverts power when it's male counterpart is plugged in. i.e. the device is running on battery until plugged in then power is diverted to that power source.

as long as the outer threaded part is thin enough that is does not come in contact w/ the center part of the atomizer connection and the pin in the center (i'm assuming there is inside?) does contact said center part, it looks like it would work nicely.

ack! someone help clarify, i'm throwing out guesses....

could make modding a whole lot easier. do you know if they have other sizes and the female counter-parts? also, where's the switch?

It's probably hollow in the center, where your + lead needs to connect.

Their pic is a lot prettier than mine, but mine has a little more detail of the important parts, so here goes

The first photo is the end that would go to the atomizer.
The second is opposite the side shown in the link.
The third is the end where the wires would go.

The dark spot in the center of the third photo is some strange membrane. I can stick a wire in it, but the wire won't go through to the center pin. It is blocked almost immediately. When I pull the wire out, it reseals itself. I have found that if I hook up the atomizer, then connect a battery pack with the negative connected to the contact you can see in photo 2 - the one without a soldering tab - and the positive to the shortest of the soldering tabs adjacent, my battery pack gets real hot real quick. Nothing happens with any other combination I have tried, even reversing this.

This is entirely possible since there is a visible seam in the center post.

ok, did a search. i imagine it looks something like this. if so it may be easy to use if the atomizer sets properly. in that case just need to check continuity of the leads to know which two to use..

ack, simultaneous post

Ok, this is where I get lost. Which leads do I use? The ones that fry my batteries or the ones that do nothing?

ack! be careful with that. you need to ohm out the center contact on the connector and see which lead it goes to on the bottom of the connector, then see which lead is ground. Make sure the center pin isn't shorted to the ground pin. The center pin needs to be connected to 3.7-5v positive and the outer casing needs to go to negative lead on the battery. hook it up like that then measure the voltage from the center pin to the outside casing. If you have 3.7-5v the connector is working. That doesn't ensure the atomizer will fit properly onto the + and - pins though. Once you screw in the aromizer quickly test for 3-5 seconds then unscrew it otherwise you may burn the atomizer up. If your battery got really hot something is likely shorted and that battery could be a goner.
