Q: jumper cables crossed car is dead

jumper cables crossed car won't turnover at all

My car has 133000 miles.
My car has an automatic transmission.

Hi there:

When the battery cables are swapped and attached to the wrong battery posts, it can and often does cause serious electrical damage to the ECU. When the cables are reversed, electrical flow is reversed, which causes an overload of electricity to critical components like the engine control unit; which pretty much controls the ignition system and fuel delivery system on your vehicle. In some cases, it simply will pop a few fuses that will need to be replaced. To know for certain, contact a professional mobile mechanic to complete a car is hard to start inspection.
