Mike, Back in the pre-alternator automotive days, new generators were polarized by momentarily touching a wire from the field terminal on the generator to the (+) battery terminal. This was done after the generator was installed and connected. This weakly magnetized the core laminations so the generator would be self-exciting. Once the generator was producing current, the voltage regulator would take over. I don't remember if the field wire from the regulator was connected or not during the polarization process. I would leave it off initially, and connect it after the generator has been polarized. This was a common practice with new generators so any older mechanic should be familiar with the procedure. Hope this helps. Dave in Alamogordo, NM
