The Lucas unit I have exhibits the same behavior as above.

Keep in mind both alternators only put out a maximum of 30-35amps.  Of course the question is:  At what RPM???

As Mark mentions, start running a hot stereo, MSD ignintion, electric fan, and hook it up to a battery that only gets exercised once or twice a week; and sure, you'll have trouble maintaining 12-13VDC, especially at idle!

Ron Earp and others have adapted newer alternators via custom brackets, but I'm sure a skilled alternator shop could re-wind either unit to output 60-90amps.
