Hi John, I remember when you posted about this before.
My suggestion is to go to a motorcycle wrecker and find
a shunt regulator from pretty much any small modern motorcycle
that has a single phase alternator. They are mostly perm
magnet, the bigger bikes use 3 phase, the smaller bikes
generally single phase.

There are only a couple of wires to connect, usually very
straightforward. Cheap, quick and should be reliable. :o)
