Chris,
I haven't seen this alternator problem show up on the Aeroelectric List.
You should go there with it.  Bob or someone will most likely be able to
tell you what is wrong.  Or lacking that, send you in the correct direction.
My only suggestion is in the future, if you have someone modify a part, you
make certain that you understand exactly what and why they did.  My
alternator guy knows alternators cold, but he had no clue when I started
talking about what I was going to do with the modification.  He knows cars,
not airplanes.  When you have 12.5 or lower volts, your alternator is not
putting out.  If it is, you will have 13 or higher volts.

I took it to my local Alternator shop and said disable the internal
regulator please.  I will make inquiry to them.
