does anyone know how to polarize a generator to a regulator
The polarity of an alternator is determined by the diode packs.
If you have a negative-ground alternator and you want to make it positive-ground (or vice-versa), you need to change the diodes. Generally that requires that the alternator manufacturer makes and sells a positive-ground (or negative-ground) diode pack for the unit.

Generator: My 78 mci had a alternator. If you have a Generator ck how in a older car manual like in the 50"s. can"t remember the sequence but can remember doing it. is voltage regulator marked F B A ?
Not sure if this helps. On the older cars and Harleys with generators, you flash (touch) the field terminal to ground, check and double check, first to be sure this is your particular case, good luck!
OK, if it's really a "generator" meaning that it is straight DC with commutators and brushes, you just need to momentarily touch hot to "F" to change polarity, or momentarily short "A" and "F."
However, many so-called "generators" are actually alternators, and I don't think any 1980 MCI was fitted with a DC generator. Specifically, Delco called the 50DN a "generator" for a long time even though it was an alternator and had diode packs.
FWIW.

Tony, I usually use a jumper wire hooked to the + - power to momentarily to touch the F-field terminal,that usually does it. HTH Glen
