OK...give me hard time if you must, but then follow up with some useful steer. In a hurry, frustrated, put jumper cables on backwards on a 2012 Mazda 3. Smelled the burning of the terminals, disconnected, reconnected them properly.

All lights come on like normal, radio works, etc, but no crank -- not even a click. Not seeing any blown fuses. Fusible link appears OK.

Any help?
