5. Try to start your vehicle (Do not have the Good Samaritan’s car running. If your car has electrical issues it could damage their car as well). If it won’t start, make sure that the cables are properly connected. Then try to start your car again. If it still won’t start, your battery may be beyond help.
6. Disconnect the cables, thank the Good Samaritan, and resume your life.
Don’t shut off your engine; drive around for a while to recharge your battery.
NOTE: Improper Connection of Cables can damage either or both vehicles charging system
