Hi all
Part of my engine swap for the winter project involves trying to keep the original alternator as it is small and out of the way.
The engine is a Ford Fiesta ST150, Duratec.
The plug is a `type 4' as per the attached. https://drive.google.com/open?id=1AVOcD7mszDG3TRVOuV3H4SNfaQZg_vds
Now, the IG 12v live and the warning light are OK, but the Signal output is my query.
Is this needed to make the alternator work? from what i have googled it just checks the batteries state of charge and then adjusts the output. Is this correct?
So, how would this be wired in on a kit car, or is it ecu controlled and has to be left out? What are the potential issues of leaving this unconnected?
If anyone is able to help that would be great.
Cheers
Steve
