Battery voltage will not display

[wireties]

Check this:

1 - Is the analog module in the slot closest to the cRIO power connector?
2 - Is the jumper on the breakout board installed? (it is the outer 2 pins)
3 - Is there a wire to running from analog breakout board to the PDB?
4 - Did you put a fuse in the PDB?

If it still does not work...

5 - Do any other channels on the analog module work? Perhaps the breakout module is kaput?
6 - Can you check the voltages on the breakout board? Is the "Power Good" LED on the breakout board lit up? Perhaps the breakout board is broken. It has some active circuitry on it.

Good luck!
