That's the part I'm having trouble with. Electrically, there is no

the positive cable, or both cables.
Hasn't been the case.... perhaps residual electricty has saved tuning
at times? Maybe Other sources of ground?
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.
