1. Weak or Dead Battery: If the battery is weak or has run out of charge, it may not be able to provide sufficient power to start and run the vehicle. When you disconnect the jumper cables, the car loses this external power source and immediately shuts off.
2. Loose or Corroded Battery Connections: Check the battery terminals and connections to ensure they are tight and free of corrosion. Loose or corroded connections can prevent proper electrical contact, leading to power loss and stalling. Clean the battery terminals and connectors if necessary.
3. Faulty Alternator: The alternator is responsible for charging the battery and supplying power to the electrical components while the engine is running. If the alternator fails or malfunctions, it may not be able to generate enough electricity to keep the engine running without the jumper cables connected.
4. Damaged Wiring: Check for any damaged, loose, or exposed wiring around the battery and alternator. Broken or frayed wires can cause short circuits or power loss, leading to the engine shutting off.
5. Electrical System Issues: There may be other electrical system problems, such as a failed voltage regulator, faulty wiring harness, or a problem with the ignition system, that are preventing the car from running without the jumper cables.
To diagnose the exact cause of this issue, it is recommended to have the vehicle inspected by a qualified mechanic or automotive technician. They can perform tests and measurements to identify the specific component or system that is causing the car to die when the jumper cables are removed.
