Hi Guppy, Sallyann, thanks for the replies. The alternator is permanent magnet, so no field windings/excitation.
Just to clarify - I'm one of the members of the group.
I'm going to try testing the original regulator on the bench with AC and a 12V battery to see if it still regulates.
The regulator should have a stable output of 14.4V under normal conditions.
cheers
