Strange. Although the marks on the bearing shells look like significant current ablated them, I tend to think that there are plenty of other paths to ground from the engine or transmission. I am thinking of how someone may have welded on the exhaust system with the ground clamp on the body somewhere, that would have caused sufficient current flow through the crank and mains that would have done that. I’m not seeing a good way for that to happen.
