Check grounding between alternator and battery post. Lack of common reference can lead to high voltage between them. Run AWG #12 between alt. case and battery ground post if necessary.

On a similar note, since battery ground has been moved to the bell housing, you also need a connection between ground post and frame (at least #12) for lights and horn.
