Residual electricity? And there are no "other" sources of ground. There is only one cable which attaches to the negative battery terminal. When you disconnect that cable, there can be absolutely zero current flow through any circuit in the car. It wouldn't matter if you were to drive a 50 foot long copper rod into the earth and run a piece of welding cable from it to the chassis of the car, the engine block, and the gnd terminal(s) of the Link itself. When the engine is not running, the battery is the only source of electrical potential in the car.* If there is no connection to the battery's negative terminal, the loop is broken and there can be no current flow anywhere. (*) Technically, the airbag control unit has a reserve power source consisting of a large capacitor built in, but it's diode-isolated from the rest of the car. Current cannot feed out of it except to the airbag controller, sensors, and detonator. Hey, I was grasping at straws. I've asked the listers because I have no explanation as to why the non-default tuning gets erased. This has been the norm for my LINK since I've owned it. As this is apparently NOT the norm for other LINK owners, I withdraw the question. **************Create a Home Theater Like the Pros. Watch the video on AOL Home.
