to the positive (+) battery terminal,
then connect the negative (-) battery
cable to the negative (-) battery
terminal.
The negative (-) battery cable should
always be removed from the battery
before connecting or disconnecting

cannot cause a short circuit if they
touch a grounded part while being
used on the positive (+) battery
terminal fitting.
