Why shouldn’t you use a car with the engine running to start another? (Page 2 ) | April 9, 2025

Essential Steps for Successful Wiring
Prepare the Cables: Use cables with sturdy alligator clips and a sufficiently thick copper core.
Turn off the donor vehicle’s engine: First connect the positive terminals together (+), then connect the negative terminals (-).
Recharge the Dead Battery: Start the donor car’s engine and let it run for 10 to 15 minutes to partially recharge the dead vehicle’s battery.
Turn off the donor engine: This protects the alternator and the electrical system of the helping car.
Start the dead car: Once the car starts, disconnect the cables in reverse order.
Mistakes to Never Make

Leaving the donor vehicle’s engine running: This can overload the alternator and damage the electrical system.
Reversing the polarities: Simply reversing the cables can cause short circuits or even fires.
Using poor-quality cables: Wires that are too thin or loose clamps can cause power losses or accidents.
Tips to avoid repeated breakdowns
Maintain your battery: Check its condition regularly and replace it if it shows signs of weakness.
Protect it from the cold: If possible, park your car in a garage or use an insulating cover for the battery.
Reduce power consumption: Turn off the headlights, radio, and other electrical accessories before setting off.
A gesture of solidarity, but with caution

Helping a stranded driver is a wonderful act of solidarity, but it must be done without compromising the safety of your own vehicle. By following best practices, you’ll avoid unpleasant surprises and extend the life of your car.
