After positioning them, clean the battery terminals of both of the vehicles so that you can make a strong connection with the cables. Put both of the vehicles in parking or neutral gear and activate the parking brake.

Importantly, you must shut everything off of your car that runs on the battery. Remove anything that was plugged in and carefully shut off the radio, speakers, and other lights and accessories.

2. Connect with the Cables

Connect the red clamps with the positive terminals of both of the vehicles and put one black clamp with the working car battery. Connect the other black clamp with an unpainted metal surface for safety.
