Wiring adjustable 510 connector

[acka]

I got an adjustable 510 rather than a sealed to make my first mod and the vamo board keeps reading 9.9ohms, no matter how high/low I position the pin. I think I haven't wired the 510 right. I basically just soldered the white output wire into the hollow of the pin and soldered the black ground to the back of the casing as I couldn't get it to the outside of the 510 (not sure if you can see in the photo, sorry). Is this wrong?

Everything else on the board seems ok. Thanks for any advice.

EDIT: It's a metal box and I just sank the 510 into the metal without a washer if this is ok. The 510 has a plastic grommet seperating the centre pin and the pin doesn't seem to be touching the sides. Not sure if anything else is relevant, this is all Greek to me.

EDIT 2: This post from Visus on a different thread answered it I think/hope

There are three connection the 510 can/will have with a metal enclosure: atomizer positive, atomizer negative, and case ground. The only way to short/problems with the 510 would be to damage the grommet that isolates the positive center pin or bridge the center pin and the shell/threads on the 510 with metal. The case will also be ground because of electrical contact with the 510 or you solder or mechanically attach a lead/wire to the case directly from the battery. You can do both if you want, the black wire soldered to the battery and a soldered wire to the case and have a huge ground, or simply just black wire soldered to the -neg battery post..

I didn't have the atty negative, I had two grounds. I'll try tomorrow with the negative on the outside of the 510 and see.

You've got it wired right by reading haven't looked at the pic closely. There's a couple possibilities. I'll start with the simplest, you do have an atty with a coil on it when you are checking it, right? Aside from that you could have a cold solder joint, or the hole around the 510 could be not tight enough to get a good solid ground

From Visus post I thought Ihad 2 grounds - 1 where the 510 hits the box and one where I soldered the neg wire to the case and so this wouldn't work? But if it would then it's probably the solder. It came off very easily and putting it against the outside of the 510 gets 1.9ohms Arrgh, it's now 3am here and I'm warming up the solder again!

Sigh. I'm a ...... I see from my post above that i thought soldering the neg to the outside of the 510 would be different to grounding but it would be the same wouldn't it? I think the hole for the 510 is tight enough, it's not a perfect circle but i need to push the 510 quite firmly down to fit it.

I just don't know why it's not working. The best I've got is having the ohms jump around from .6ohm to 2.xx when holding the neg wire in different places manually but if i try to fire it will either say overload or short.

Maybe I fried the board. I soldered on external switches before removing them due to space and after it wouldn't switch on at all but after redoing the neg battery wire on the board it came back to life so i thought it was all good. Otherwise everything looks good. All options and buttons work, it reads the battery v etc.

If i place a multimeter on the board at battery pos and neg i get 3.8v.

If I place it at the ends of the 510 wires and fire at 3.7v it reads about 6.5v, don't know if this means anything.

Could i use a atomizer/coil to check if it's the 510 that's the problem does anyone know? Or some other check.

I should have gotten 2 of everything

I realise I'm talking to myself but it looks like I fired the board. Superficially everything's working but it's just not happening at the last yard. I cannabalised an old ego to use as a 510 and had the same problems.

I had my suspicions when I saw smoke and sparks coming from it after a bit of 'skilled' soldering but strangely that actually kicked it back into life.

Oh well, a four week wait from Ft and then it should be good to go. Next one will be PERFECT

tough break, too bad for your board. But like you said, next one will be perfect. Im working on my second wood box mod for a sx350 chip. pretty fun, helps to have messed up in the past. good luck!

The replacement board arrived today. Took a little more time installing, was more careful with everything and wrapped it in Kapton (sp?) tape and it's up and running. Actually very pleased with myself

Shouldn't really post any pics of it considering the quality of the mods you guys make but fck it, it took me long enough.

Next to a box of stinkies (not mine, honest - haven't touched one in 6 months)



Soldering external buttons was a step beyond my ability, I had to cut out the box. Nice long-distance pic of that I think, skip the close ups.
