Hi all,

Well, after 42 years of owning a '64 3000 MkIII, I've decided to replace the 
generator with a Delco SI-10  (NAPA #21341001-148 63amp) Alternator.  Although 
seeming to be a simple conversion, I have not achieve proper charging and need 
the perspectives and suggestion of those who have successfully achieved this 
conversion.  
 
After having the re-rebuild alternator checked for the third time by a 
professional, I am reasonably sure that the unit can operate properly.  Based 
upon this assumption, and the fact that my Volt meter readings are 12.8V at all 
RPMs, I must conclude that there is something incorrectly set within my wiring.

Summarizing, 
the Healey has been previously wired for Neg. Ground and the following wire 
connections have been secured on the Alternator:
  1.  Ground contact established through the engine plat via the Alternator 
conversion adapter.
  2.  BATT terminal - Directly wired to Battery side of the starter solenoid 
with (2) 10-gauge lines (2 used just to be sure).
  3.  Terminal #1 - Connected to the NY line and, via the indicator lamp, to 
the switch.
  4.  Terminal #2 - Connected to the BATT terminal.

As many converters have done, I have maintained the old regulator as a 
distribution point for both the N (brown) and NY (brown/yellow) wiring.

I would appreciate any suggestions that will move me toward a resolution.

Thanks all
