<VV> voltage regulator Answers

[shortle]

Hi Frank, It seems I remember the expression "feed the field" which I thought meant giving a touch of battery voltage to the F lead at the generator. This (sort of) put the generator and the regulator on the same page? Please enlighten me on my older fading memory. BTW, today April 18 is my older brothers 60th birthday. I never thought anyone could get to that ripe old age!
