The alternator has been rebuilt and tested and is operating to specs on the test bench. It does not charge in the vehicle. Is there a diagnostic flow chart or diagram to test the transistorized voltage regulator in the trunk. It has a new battery and the wiring has been checked for continuity and resistance. Thank You

This is the first Rolls Royce car I have advised on mate. Have you tried substituting a known good voltage regulator for the original? I do not have access to diagrams for Rolls Royce cars, however it seems the regulator is suspect.
