Battery problems - ODIN DNA 250c

[Darkabyss]

Last night my Odin DNA 250 decided it was going to start throwing up check battery's.  Upon hooking it up to EScribe this morning it seems the battery's even though fully charged (multiple sets tried) are averaging around 1-3 Volts each. I've included a screen shot.  Any help would be highly appreciated.

The cell voltages are being read from the balance tap. Check yours if you're able to. Check the condition of the solder joints as well as if any e-liquid is present. 

G,1, 2,3, and 4.

thanks for the reply @dwcraig1 

 

ive stripped it down and cant see any liquid on the area you pointed out, but upon looking the board is shiny? is this a coating on the board or baked on e-liquid?

There is a conformal coating on the board to help protect the components, but ejuice can deteriorate a connection at the solder joints/connectors.

Did you meter out the connections identified by Dwcraig like he suggested.

While I mentioned checking for liquid on the board I was more concerned with the solder joints. How do they look? Do you have a volt meter? 

[Darkabyss]

Sorry for late reply,

looking at the solder joints there clean, checked continuity across pins 2-3-4 no problems there, but the wire that runs from pin 4 to main positive(tiny sliver of red wire) no connection across that wire, could that be the problem? 

[Darkabyss]

I've marked the solder joints and wire I am referring to 

[dwcraig1]

2, 3, 4 and B+ are bridged together. That is how I wired mine. Replace the wire going from 4 to B+ or solder bridge it and you should have it working again.
