I am throwing a hail mary on easter here...but when you say you did a parasitic draw test....did you use the meter and pull each fuse one by one? Just want to make sure a step wasn't overlooked...
i'll assume the poster removed a battery connection, and placed a ammeter in series with it
therefore did a total load/current draw for the car
