The lack of units has already been mentioned, but I have another question.
You put a multimeter to the frame and what? If both probes were on the frame, the resistance would be 0.0, or close to 0.0, as would the voltage (due to the fact that the resistance is 0). The proper way to test for electrical continuity problems is to , with the meter set to measure in kOhms, place one probe on the frame while the other one is placed on the cRIO chassis, the back of the axis camera, motor controller outputs, and the PD board inputs (Make sure the robot is off, or preferably, the battery is out of the robot. ). If the meter displays infinity (usually a 1 at the far left of the display) in all cases described above, but 0.0 when the probes make contact with each other, then the electrical system is likely not shorted to the frame.
