You may have stumbled onto a solution, and I am really happy you did. When you remove power from the system and then hook it up again it can get mixed up kind of like when you boot a computer sometimes you need to do it more than once to get it to initiate.
The aftermarket industry has come up with all kinds of "memory saver" devices designed to allow the battery to be replaced without having to go to the dealer. Some just plug into the cigarette lighter, but you have to have a car where the lighter works with the ignition switch turned off.
