Regarding the Hitachi alternators, I believe these are "N" type alternators.
The smart regulators made by folks like Xantrex only work with "P" type
alternators. I think this N/P business is something to do with the way the
diodes are wired. I think you can make the necessary changes in the Hitachi
but it may not be cost-effective.

Anyone out there have any experience or words of wisdom to offer on
removing the internal regulator from a small alternator like a Hitachi
LR135-31 so as hook up an external unit that will properly charge GEL or
AGM batteries?
