Mike,
Glad to hear to finally nailed it.
I've had screwy electrical problems also - but lacked the patience and perseverance that you did. After one pass through the system using the kind guidance of folks on this board, I stopped throwing money down that hole and converted the system to the series 400 paralleling regulators. Problem solved - and the alternators are now balanced. I've been running about 30 hours now with the new system. (Anyone considering this - make sure you work in advance with the FSDO - they'll have lots of questions and reservations. But if we could get this through Oakland, you ought to be able to get any FSDO to come around).
I suspect the lack of a sense line between regulators in the original 337 design is what makes it so sensitive so to any kind of resistance differences between the two circuits. With feedback (as in the 400 regulators), this will adapt for variations. Of course, the ideal situation is to have clean resistance-free connections regardless of which regulators you use.
