Hi,

This definitely falls into the other topics heading.


I have a Shibaura Alternator assembly and Regulator that I acquired for
my sailboat diesel engine.  It's a permanent magnet type Alternator part
# 185046210 and Regulator part #185516060  (Just in case someone has the
correct manuals).  I was told it's a 15A Alternator.

The Alternator has two Blue leads that create the AC for the Regulator.

The Regulator has six wires:

two light Blue
Black
Red
Yellow
Green

Can anyone look up in a Service manual for a garden tractor or some
other engine that might use this type of Alternator/Regulator and
perhaps identify what wires go where?  I would imagine most of the units
out there using this type of alternator probably have a similar wiring
mode.  What would be the maximum RPM of this type of Alternator.  I've
tried the searches on Google etc. and lots of tractor links among others
but nothing shows up that could help me.

I'm guessing that the Regulator blue wires go to the alternator.  That
the Black is ground and the Red is to the battery.  That leaves yellow
and green.  One is probably an alternator light and the other ????

Anyone have any idea how this type of regulator works.  I'm thinking
shunt type that just clamps the voltage at a preset point. Or a series
pass that regulates the output and just allows the output to go to
maximum under no load conditions.  If worse came to worse I could scrap
the regulator and roll my own but for convenience (I'd rather go
sailing) it seems easier to use the existing part.

Thanks,

John
