Suggestion 1: You don't need to remove the starter motor from the vehicle to perform the test steps in this article/tutorial. The photos I'm using show it off of the vehicle just to make it easier to show you where to make your connections.
Suggestion 2: The battery in your Nissan needs to be fully charged to perform all of the tests. Also, the battery cable terminals and battery posts must be clean and corrosion free.
