Aletrnator Regulator

[jackworstell]

I'm looking for a generic schematic for an alternator regulator.   One that can be
adapted for 6v or 8v or 12v   positive ground or negative ground.   No doubt it
would have to be an external regulator.   

My immediate need is to convert a 6V CS 121 unit ( positive ground ) to 8V.  Of course the internal regulator
would have to be dispensed with.

I suppose the internal regulator is potted, by that I mean it is incased in plastic.  If not, then you might be able to change a couple of components to change the voltage.  To change the polarity, you would have to reverse the diodes.  But I have no idea what that would take or if that is possible.  I have not been inside an alternator in years and I was only changing diodes.

I believe you must have the correct polarity regulator, 6V or 12V
for the alternator.  HOWEVER, you might tease a 6V regulator into
working well at 8V. 

Here all electronic alts have 2 small control terminals, besides the
big output stud.  One control wire is marked 1 or L, going to the GEN
light.  The other wire (2) normally goes to the battery terminal
voltage, sometimes tied to the stud.  It is used to sense and regulate
the voltage.  If you insert a small resistor in series with 2, it should
shift the voltage into the range you need. 

Don't have your alt, but suspect something like 100 to 1000 ohms is
the right range.  I would insert the resistor, and running adjust it till
you see 8V at the battery end of the resistor, 6V at the alt (2) end
of the resistor.  good luck, Bruce Roe
