Dna20 help

[Jason_brent]

I have gotten my dna 20 all wired up all the buttons are working now i am just having a problem getting pass the "CHECK atomizer" warning i have a rba on it and the rba works fine on an Ego but then i try to put it on to the mod and it tells me to check the atomizer i dont have any other kind of atty right now that i can check it with just wondering if any one else is having the same problem
the chip is showing an ohm reading but still says to check the atty i am ready to go nuts and cant figure it out if any one out there can shed some light on it i would be thankful

maybe the ohms are too low? what ohms are you running? also, see if raising the wattage helps...the dna20 only goes down to 3.5(ish) volts and if you have a lower ohm coil it could be tripping the low end.

If what jmarkus suggested isn't the issue, try looking at the connectors to make sure your making a connection. I have seen both female and male connectors vary to where certain combinations don't work together.

Do you have a way of measuring the female connector depth versus your RBA male connector? Or if your RBA has an adjustable center pin you could try increasing the length a little.

at first it was showing 1.30 ohms but now its not showing any thing i pulled the connector apart and worked on that made sure the connection was good I re wraped the coil not sure what the ohms are now but they should be more than what is needed i am using 32 gage Kanthal and wrap it 5-6 times so it should have enough resistance but i am about to put it together again and hope it works



just tried it again and so far its not getting any ohm readout it says that the coil is at .8 but i know better
so i just need to work on the 5-10 connecter its self i had the same problem with the last chip and didnt get to finish this project cause it got smashed this is really ticking me off

Do you have a dmm to test the coil resistance with the atty all put together. I'm just guessing, but it sounds like you may have something funky going on with your atty. Other than that you may want to start at the 510 connector and work back to the DNA checking connections and etc.

I haven't experienced or heard of any weird ohm readings with the DNA, it wouldn't hurt to contact Evolv and see if they have.

I had a problem like this with mine and it turned out to be the wires I was using to jump the battery to the board and the leads from the board to the atty where to long. After I shortened them up everything worked out fine. Also make sure your wire gauge is adequate
