alternator wiring connectios

OK - im ready to connect the 70+ style alternator ( marked 2 flds connections ) on my 69 cuda with original wiring and regulator- will connect grn to alternator fld and a-jumper from the other fld to grd. MY QUESTION : there is 8 volts at both fld-terminals when grn is connected ( 2nd fld not grounded ) with engine running ---will i fry the alternator / wiring - if this is grounded? is it not a direct short by internally regulation - any thoughts? hep out there? cudanutz
