To replace the alternator on a 2000 BMW 740iL, first disconnect the negative battery terminal to ensure safety. Remove the serpentine belt by using a wrench on the tensioner pulley, then unbolt the alternator from its mounting bracket. Disconnect the electrical connections on the alternator, then install the new alternator by reversing the removal steps, ensuring all connections are secure and the belt is properly tensioned before reconnecting the battery.
