Any ideas why the drivers station has VOLTS 00.00 when everything is powered on and running?
You need to install a jumper on the analog breakout board in slot one:
A National Instruments 9201 module must be installed in slot 1 of the cRIO-FRC . An analog breakout must be connected to this module. A jumper must be installed in the “Power” position (two outer pins) on the analog breakout. The analog breakout must be powered from the PD Panel. (Please refer to the 2011 FRC Control System Manual for details on these connections.)
These connections enable monitoring of the battery charge by the team and the Field Management System. This is a required element of the ROBOT configuration.
below that quote is a picture highlighting how the jumper should be installed.
You need to install a jumper on the analog IO module for input 8. This jumper routes the voltage to input 8. This is required and is mentioned in the documentation.
