A fix for first gen VTR's and the NON error

[DaTank]

I haven't seen this posted before, so here it goes.

I got a few broken VTR's to cram a DNA30 into, and started poking around. Both I received had the dreaded NON error and were first gen VTR's (The spinning ring). A DNA30 with a bad connection is no use, so I ripped one apart to diagnose it.

Photos of the 510 connector and the parts are here:

There are 2 pins in the first gen connector; one you can see, that floats in the insulator, and another that butts to it below it. The bottom is spring loaded, and under ideal conditions pushes against the floating connector to make the connection for the positive side of the connector.

Unfortunately, if you carry your VTR around you can get gunk and other crud built up between that connection. As the connection point between the two gets smaller, you get the resistance fluctuating, until eventually it severs the connection.

This means, if you yank the pin out, you can stick the thinner portion of a qtip down in there and clean the crud off. Then you get things back to normal. I just did this on one of the VTR's and went from completely non-functional 100% NON error to working perfectly regardless of how I rotate the ring.

I initially assumed wrongly that you could not clean that pin without ripping it apart like I did in the the first album. Thankfully I was wrong

I bought my VTR used but looking close to new, but it was plagued with wheel issues also.
This is the first advice on a fix for my mod that I really liked, but bad resistance readings made it very unpredictable in wattage mode. I even had a thread on suggestions for a fix on these forums with no real help in fixing it.
Pulling the pin took a bit of work which I did with 28 gauge kanthal and needle nose pliers.
It actually looked rather clean under the pin, but I scrubbed it well as suggested and it's reading a 100% constant resistance now.
Thanks for your thread I now have my VTR back to like new

Glad I could help! I'm surprised by the lack of response I've gotten, as threads while I was researching this issue were filled with people that had this problem.

Thanks for the tip.
It took about 5 minutes and is working like a charm.
The local vape shop where i bought it from kind of ...... me off some,because i took it back the next day and they were all like,"just send it to the manufacture and you're all set".
I was like,You're not even gonna back up something you are selling for 1 day?

I ended up buying the updated fixed version from their competition and was gonna dive into fixing this one,one day,but it's nice to see there was no tearing apart that had to be done to it..

Awesome help,Thanks a lot

I'm so glad I found this! I got a VTR today in the mail that I got from the classifieds, and I kept getting the NON error more often than not. I'm not a very patient person, so I thought why not, I'll try to fix it myself, and if it breaks, so be it. LOL It took a lot of work to get that pin out, but I cleaned what I could find, and pushed it back in, and it seems to be working well now, switching from tank to tank, where I'd get the error a lot in between before. Someone said that the early one's connectors stripped pretty easily too, so I read about and then ordered a couple air flow connectors that also act as a 510 to 510 connection that I'll just leave on there when they come in.
