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.


Basicly a "N' type alternator has the regulator hooked into the
Negative side of the alternator where a "P" type will be hooked to the
Positive or "IN" side.
It denotes which side of the alternator the regulator switches from.
