Can anyone give me info, or a site to get info for converting a Delco
alternator from internal voltage regulator to an external regulator?
I have been using a slightlly modified Delco 108 amp alt. for 6 years, with
homebrewed manual charge controllers, and am thinking of trying one of the new
smart regulators.
Any help would be appreciated, Thanks

There is a book called "The 12 Volt Doctor's Alternator Book" by
Edgar J. Beyn. It details many types of alternators and perhaps your
unit is in there. Seems like a pretty straightforward to remove an
internal regulator. It sounds like from your description, the alternator
you have does not have an internal regulator. In that case you only
need to be able to connect to the field terminal to use most
any smart regulators.

The 108 amp Delco alternator I have does have an internal regulator. I can't
remember if the 12 Volt Doctor's Alternator Book talks about this conversion.
Ed Beyn is the man for 12 volt info.
I made my first manual controller, back around 1990, after talking to him at
his shop in Annapolis, and following his instructions. A wire and a lightbulb
were all that was needed!
I'll hunt down a copy of his book.

I have a scanned copy of The 12 volt Doctor's Alternator Book at

BTW, I'm running Delco 100 amp alternator with the internal regulator
still wired in parrallel with my (Plath/Beyn) AutoMac II (semi)smart
charge controller. It's just connected to the field brush terminal of
the regulator. This is the way that Beyn recommended in the installation
instructions. Works great on my ~800 AH battery bank. If the alternator
runs to hot, the charge current will be reduced or if necassary it will
drop the charge back to the internal regulator.

Alternators don't have brushes

Mine does - but they run on slip rings rather than on a commutator, so
they experience less wear.

The brushes and slip rings carry current to the field winding which is
mounted on the shaft.

Unfortunately you are wrong.

Nearly all A.C. generators, i.e. alternators, use brushes to transmit
exciting current to the rotor. The A.C. output is taken from the
stator. In the case of an automotive "alternator" the stator output is
then rectified by diodes mounted in the end plate.

The exception would be in something like a wind generator where the
rotor is a permanent magnet to avoid the cost of excition current.

Try a google search on "alternator brush" and get back to me

Oops! My mistake. I was remembering an alternator that I disected
a few years ago that didn't have any field brushes. Taking a quick peek
at the book, I see that many alternators do have brushes for the
field winding. Sorry about that. Hey, I said that alternators DON'T have
brushes BEFORE I said that they DO have brushes. Guess I pulled
a Kerry
