the good battery’s
negative (-) terminal.

The electrical connection is just as good there, but
the chance of sparks getting back to the battery is
much less.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably
needs service.
