Autozone Electrical System Check (Reversed polarity)
I have a 2006 Toyota Corolla which the Toyota dealership claims has damage caused by jumping the car incorrectly. They say the car was damaged due to reversed polarity. I took the car to the local Autozone to have a free electrical system check before
With Toyota's if the polarity is reversed it will blow the 100 amp fuse and usually the 15 amp EFI. These protect the more expensive components. I have personally seen the polarity reversed briefly with no sparks, smoke or battery explosion. Jumper
