How to check for a short

[Outcast]

I got myself a bunch of wire and I'm going to be trying some crazy build this weekend hoping to get a fused Clapton done
Will the ohms meter what you know have a short or what what to do if you did in the meter

What meter do you have?
Are you familiar with how it operates and what the setting and readings mean?

Be safe

Just one you screw the 510 in to our shod I go to Lowe's and pick up a Multi meter ya little bit would it just be continuity on the multi meter if you have continuity you should be good right
I did not know if a normal ohms meter would err out our something

The one I have now don't do good on low DC

Are using a unregulated box mod with no fuses so I just won't to check before throwing it on

As long as your batteries are up the the task you should be fine. Personally, I would stay above .2Ω.
Use something like http://www.steam-engine.org/ and confirm that your meter is accurate.
For me, a "short" would be anything that is pushing my battery beyond 80% of it's rated discharge rate.

Have fun

Unless I'm missing a setting in steam engine I can't seem to have it set up for dual parallel box with my batteries they only give me the rating for one battery

in parallel, you basically have a LARGER (more mAh) battery.
Voltage is still 4.2 , amp draw is divided between both cells but the AMP limit per cell does not change.

Ya 20 amp cells gives me 40 I got that thanks man

My brain sees it like this: load (amps draw) will be shared by both cells, but each cell is still constrained by it's own internal resistance/amp limitation. 20 amp cells/20 amp limit (well 80% of that to be safe).
I would not attempt a 40 amp build with 2 parallel 20 amp cells.

i also use a torch to shine in through the driptip and then through the airhole to visually check how close the coils are to the side of the topcap and then check ohms for shorts also with cap on and off.
There are a lot of attys that lose a lot of deck space once the topcap is installed, dont take it for granted that they are all the same.

I just didn't know if there is a way to check to make sure that your coil wasn't hitting Side Of the RDA our something stupid like that if the ohm meter would show it somehow was all I understand battery safety

For those of us in the united states, torch = flashlight.

yeah check the ohms without the topcap and then if it changes with topcap on then you are possibly touching the coil's on the inside of the topcap, if you are using a multimeter you can test the ohm on the 510 pin when the cap is on.
And yes sorry i ment flashlight

Its no worries, I just pictured thousands of vapers this side of the pond trying to figure out how you safely use a butane torch to check for shorts.

That IS the image that popped into my head.

Easiest way to check your build for shorts is with one of those plastic ohm checkers. Put your rda or whatever on it, when you have it built, check it. Install cap, check again. A short will show up if there is one. Then you know its good to go.
