Can A Jump Start Damage Your Car. Lets say you put the cables on correctly. You can cause expensive damage to your own car simply by providing a jump to someone else.
Crossing the jumper cables can blow fuse or completely fry the vehicles. A questionable alternator battery can perform fine for a long time. The simple answer is yes.
Dealing with a dead battery in a modern vehicle requires new equipment and techniques.
Never jumpstart a battery if fluids are frozen. But if youre doing the jump with your car just idling your alternator isnt turning fast enough to put out all it can. Electrical systems in modern cars run everything including steering airbags brakes and entertainment systems so the cost of repairing any damage could go far. Im not talking about the kind of damage you can inflict by hooking up the jumper cables incorrectly.
