Here are some possible reasons why the engine might die when removing the battery cables:
* Loose or corroded battery cables: Make sure the battery cables are tightly connected and free of corrosion. Loose or corroded cables can cause poor electrical connections and prevent the engine from getting the power it needs.
* Faulty alternator: If the alternator is not working properly, it will not be able to provide the engine with the power it needs to run. This can cause the engine to stall when the battery cables are removed.
* Faulty voltage regulator: The voltage regulator controls the amount of voltage that is supplied to the electrical system. If the voltage regulator is not working properly, it can cause the engine to stall when the battery cables are removed.
If you are experiencing this issue, it is best to have the vehicle inspected by a qualified mechanic to determine the cause and make the necessary repairs.
