"generator or regulator"
I haven't seen those referenced for quite a while. Alternators replaced the generator/regulator combination sometime in the early 70s if I recall correctly.
Diagnostic codes are the proper way to diagnose and service modern vehicles, workarounds are possibly suitable for field repairs until you can get to a technician. I sold my 54 Ford, I've never looked back.
