When the battery bracket is broken, the battery can move around and become loose, which can cause the alternator to not charge the battery properly. This can lead to a loss of power, as the battery will not be able to provide enough power to the vehicle's electrical system.
Replacing the alternator may not be necessary. If the battery bracket is the only damaged component, replacing the bracket and securing the battery properly should restore full power to the vehicle.
However, if the battery has been damaged due to the movement caused by the broken bracket, it may also need to be replaced.
