Alternator Charging Problem

[D]

Hey All!

I've been experiencing intermittened charging from my Leece Neville
A0017704JA alternator and now not getting anything out of it. I had
it rebuilt about 2 years ago (7000 miles) and this last summer my
voltage meter would hit 14 volts for a short few minutes and then
dips just under 12 volts for a long time (night time driving). With
lights off my voltage hovers around 12 volts.

This alternator has a pig tail on the regulator which I figure is the
trigger wire (14 guage)? It appears to be live (12 volts) with key
off or on. So this has been on All The Time. Wondering if that wire
being energized all the time could damage the regulator or
alternator.

I am wondering if this could be a malfunctioning battery isolator.
I'm rambling with lots of ideas without being able to try them out
from my office.

Any thoughts? Thanks for taking the time to read my lengthy query.
