Post subject:  HV Battery Drain Down

My HV battery loses about 8-10 % charge every night (when not connected to charger). I have found that when the key is switched off:
The "P" light on the shift indicator remains on
The battery coolant pump continues to run
The DC to DC converter is still charging the 12 volt battery because the measured voltage is 14.6 volts

Obviously, because these things remain on, they are causing the drain on the HV battery.
I have also disconnected the 12 volt battery and everything shuts down and the HV battery no longer drains.

Does anyone have an idea as to why turning off the key does not shut things down?
