My dad has a 2019 6.7 and the other day a pack rat got into the engine bay. He must have got caught between the belt and pulley on start up cause it threw a the belt and split him in half. Re routed the belt and check pulleys to make sure they are good. Everything seems fine. No loose/bad wire I can see. Alternators are good. Batteries aren’t loose but it is throwing codes P0625 and P163C both are generator circuit codes. Any help on what it could be? Also can’t find any fuses bad.
