So if you measure the current from the Power Distribution Board to the cRIO, it should not go past .83A. If it does, then it's the cRIO, if not, it's the PDB.

Actually, the wattage of the cRIO would stay the same at 20 watts and the current would INCREASE with a lower voltage, so if the main battery starts running really low and the converter isn't running as efficiently and not outputting 24 volts, perhaps 22volts or 20volts the current would increase proportionally. so the cRIO could possibly draw more than .83A.
