Marshal voltage regulator question

[D@vid]

Hi guys,

I'm having problems with my (original to the car) external Marshal SEV voltage regulator.
The correct replacement part seems to be Part#: 911-603-901-00-M262

Am I correct in thinking that:
the blue wire goes to 3
the brown wire to 2
the black wire to 1

Many thanks,

David

Yes I think you are correct.
Ground (brown) is definitely the middle terminal (2).
Black goes to terminal labelled "Field" (FLD) (1). Might be labelled DF.
Blue goes to the remaining terminal (3). It may be labelled D+.
