Rob..... ...yes, that is the correct "polarizing" proceedure for 8N 3-wire genny/4-wire V/R. The reason it works is because of electromagnitizm. ibid...see theory of EMF. All magnets have what is commonally called N & S poles, electomagnets too. Except electromagnet poles depend upon which way the Direct Current (battery) flows. When you "polarize" your genny, you magnitize your field poles for the way that your battery is hooked up. Then when the armature rotates thru the "field" it creates "correct" current flow which charges the battery. The voltage regulator senses this charge from the genny and compares it to the battery charge and if the genny armature output is too much charge, the voltage regulator "turns off" the field magnet for just a moment then back on. Infact, the voltage regulator was often called a vibrating regulator. And seriously, if you want to know more about generators and voltage regulators, go read a book..... ...respectfully, Dell
