Why is it important to disconnect the battery ground cable before working on the electrical system?

Disconnecting the battery ground cable before working on the electrical system is a crucial safety precaution to prevent accidental short circuits and electrical shocks. The battery provides the power source for the entire electrical system. By disconnecting the ground cable (typically connected to the vehicle's chassis), you effectively isolate the electrical system from its power source. This prevents current from flowing if a tool or wire accidentally comes into contact with a grounded metal part of the vehicle wh....
