Started up my BJ74 and something spun really fast and I could smell something acrid, then the loud spinning settled down to normal. Not sure what that was but I made it home no problem. Went to start the truck and it struggled to start for a second but started up. Heard the fast spinning again and there was the smell again so I backed up a little and some molten metal fell down from under the engine. The particles looked like copper. I stopped the truck, crawled under and saw this: Now the truck won't start at all, just a clicking noise so I'm really thinking its the starter.
