[Saloon-lovers] Voltage regulator query

I’ve just had the voltage regulator replaced on my 1966 3.8 S type.
The new one is a Lucas one - just like in the pictures in the
workshop manuals. But it was only when the garage pointed it out to
me that the old one was ‘some weird Japanese one’ - it is an F.D
one, stock no LUR 270/12 - 1.
The ammeter behaves a little differently with the Lucas one than
even in the distant past with the F.D one - so I suspect the inner
workings to be rather different.
However, out of curiosity, I am wondering whether the F.D one may
have been an original fitting or was fitted after a previous
problem with a VR. Outwardly it looks to be of a fair vintage -
fairly crude and bulky, and about the same size as the Lucas one.
The car concerned is a South African assembled model, and I have
been led to believe there were some differences in equipent over
the standard versions. Does anyone know if the Voltage Regulator
may have been one of those differences?–

I’ll send you a picture of a n.o.s. spare Lucas Regulator which is
identical to the one installed in my S type, which looks to be
original and which matches the ilustration and description in the
Factory Service Manual.

How is the ammeter behavior different with the Lucas Regulator in
your car?
