The simple answer is that if the alternator is wired correctly, and has NO problems with it's INTERNAL diodes, the EXTERNAL diode SHOULD NOT affect current draw with the engine STOPPED.
The diode in the lead to the #1 "switched excite" terminal simply prevents current from the power supply for the rotating field INSIDE the alternator from "backfeeding" into the ignition system, preventing the engine from being shut down.
Once the engine IS STOPPED, there is no current being produced inside the alternator TO backfeed, and the diode should have NO voltage on either it's anode or cathode, and be serving NO purpose, at that time.
To recap, if the alternator is good, and wired correctly, the absense or presence of the diode has NO effect, ONCE THE ENGINE IS STOPPED.
