Simon S gave a good explanation of what you need to do to start, and hopefully this will isolate the issue.
One more thing: if the battery drain problem is due to a relay or transistor switch staying "on" after the car is shut down, but the problem goes away on a power reset, as with "skibumm100's" son, then you are going to have to find some way to maintain power to the ACC circuit. A way to do this is to figure out how to pull off one of the battery terminals while maintaining continuity of the connection, i.e. by keeping one meter probe touching the base of the battery terminal and the other on the battery clamp while it's being removed. Hope that this makes some sense.
