Maybe this info can be useful.

Question:
Does the +4 Duratec 2L MY 2009 adopted the "Ford Smart Charging System" (smart alternator, where the charging voltage is regulated by the engine ECU)? This system was common in Ford cars (also Mondeo) since the 2000's till present times. Or does it have ordinary charging system with the voltage regulator embedded in the alternator?

Answer by MMC:
After speaking with our technical department I can confirm that the alternator on your Morgan is indeed a smart alternator.

I have a 2012 Duratec Plus 4 (built 2011), I changed the ECU from the Ford Visteon to an EMU Black ECU from ECU Master, this stand alone ECU has no smart charging function.

As we can see from the following log taken from my EMU Black, the alternator regulates perfectly around 13.6v

To me this proves the Ford Visteon ECU used by Morgan had no smart charging function either.
