DNA 20 Troubleshooting

[vinnyvango]

Hello Folks:
I'm hoping someone can help me trouble shoot my dna build. This is my first dna project. I've been following the instructions the imminent Mamu posted for the Milo build. I soldered everything up with short leads and mounted the chip in the case for final fitting and trimming of the wires. At this point I thought it would be a good idea to test it. The chip powers up and the adjustments work fine. The battery reads as full and the resistance is displayed. But when I engage the fire button I get a "Check Atomizer" error. I get no continuity between the 510 post and housing.

I'm stumped.

Thanks for the help!

do you have an atomizer on it?

^^^^what he said

 

[vinnyvango]

Yep. There is an atomizer (2.3 ohm) and the dna displays the resistance. But I get the check atomizer error when I press the fire button.

I guess I should also note that the wires are just twisted together. Not sure why that should matter.

It could be your twisted wire connection. I would try soldering or using wire nuts for a temp connection. Also make sure your center pin is making good contact in the connector. A barely touching center pin or loose twisted wires may provide a good enough connection to read the resistance but not handle the load when pressing the fire button.

The power out wires to the connector are soldered directly to the board. I'll try soldering the others. Thanks.

Well.....I soldered the connections and got the same result. I wiggled the OUT wires in an attempt to check for a cold solder joint. They appear to be well fixed. Any other suggestions? Could it be the battery? I'm using an 18500 EH IMR right now. Gonna try a AW IMR when it charges.

Thanks.

I guess it could be the battery, but I would figure the DNA would throw a battery error instead. That's definitely something to try.

What type of atty are you using?

Have you tried different atty's?

I'm still leaning toward a light touching center pin or if a rebuild-able atty possibly a loose or touching coil connection.

yeah, the dna20 is pretty good at telling you whats wrong...so its either your atty connector, or the atty itself.
