Car won't start nothing electrical works when key is on or off. I tried jumping still no power comes through system. Battery is good, tried head lights and other items none work. Won't turn over or show signs of life. Also checked battery connections they are good and battery has power it's like there is something from keeping power to the entire car.

Take those cables off, and remove the bolt.

There is a thick lead washer, about 3/8 think.

A really hard greenish/blue deposit builds up on the washer and also on the cables that will not let electricity flow.
