Re: Reading Battery Voltage
Ground can be found in many places on the robot.
The easiest (most obvious) is the black terminal of the power distribution board or the black side of the battery. Also, you can use the ground terminals on the analog breakout, or any of the number of ground pins on a digital sidecar (properly wired, of course).
Aside from that, I'm pretty sure the cRIO chassis will work, or a black terminal on a Jaguar, or the black terminal on a spike.
Like I said...many places. Just make sure you're using a multimeter in voltage mode, with the probes plugged into the voltage pins. You don't want to short anything out by accident.
