39. Follow the Exact Jump-Start Order for Modern Electronics

Modern cars have sensitive computers, so jump-starting must be done in the correct sequence: connect positive to positive, negative to a grounded metal point away from the battery, start the dead car last, and disconnect in reverse order.
Doing it wrong can fry electronics costing thousands. Experienced drivers keep jumper cables with clear instructions printed on them and always follow this order. It’s the difference between a quick rescue and an expensive tow.
