they both DO NOT apply to the same type of field circuit.
you can't use generic info, mixed togehter like cookie dough, and then apply it to stuff it does not apply to.
i gave you info in my last post how to determine what circuit type your reg is. if that reg is the specified one for your machine..and you have the oem genny.. then you know what circuit type the machine is.
from there.. you know how to polarize it
( bat to arm, when not running polarizes 'A' circuit.... when running, field to ground provides max charge test )
( bat to field, when not running polaraizes 'B' circuit.. bat to field when running provides max charge test. )
throw that note you have away.. it's only good for roasting vregs.
you can't blindly sift thru a forum for generic electrical info and then HOPE it applies to what you are looking for. do your tractor a favor.. get a service manual for it. it will love you for it. :)
