I know myself, I am defintely not carefull. In fact I have 3-pin
connectors with both +/G/+ and G/+/G arrangemnet. With fools diodes
everywhere I just try both :)

Shorting a modest current (a few Amps) will not produce much heat (zero
ohms = no voltage = no power). If you would instead connect a small
resistor (both physically small and small resistance) things will likely
be different.
