If the alternator is putting out too high of a voltage, I 'm not sure anything external could cause that. Anybody know if replacing the charging bulb/resistor to the exciter "wrong" could cause this, or some kind of short?
What area are you located in, maybe we can stir up some local help?
Put some spaces in that monster post.
How were relays checked?
I would start with a careful cleaning of contacts on the pod, grounds etc.
