No, The only difference is the method of polarising between an INTERNAL
grounded generator and an EXTERNAL ground generator.
To determine which system you are dealing with look at the brush holder
that is connected to ground. An internally grounded gene will also have
ONE of the field leads connected to it,an externally grounded gene will
have no other wire connected to the grounded terminal. With an INTERNAL
ground (GUZZI) you polarize by DISCONNECTING the FIELD lead and
MOMENTARILY touching it to the BAT terminal on the regulator. With an
EXTERNAL ground you just momentarily connect a jumper wire from the BAT
to the GEN or ARM terminals of the regulator.
I have seen many situations where every thing else looks ok but the
generator was not working that were remidied by repolarising. When
working on old fork lifts and cars from the 30s to the 60s you see all
kinds of malady ,some caused by reverse connection of jumper cables or
the battery itself
Folks take the generator apart to replace brushes and after reassembly
fail to re polarise. Do it by the book and avoid simple problems!

OK, this is not Guzzi related, but perhaps one of you electrically minded types can help. I have another old bike that will shortly be getting a new generator. It is a six-volt, POSITIVE ground system. Does this affect the polarising process? Jay Williams Another cause for loss of residual magnetism is disassembly of the generator. You will often get by without doing so but it is easy to be sure! This is why they always recomend polarising rebuilt generators. The short story is there is no harm done by polarising so ,if you have had it apart or have any reasson to believe you may have disturbed the magnetism the effort to polarise is well worth while.
