If its like my 59 the heavy gauge wire runs to the starter or to the batt. the lighter wire goes to the volt meter on the dash. If you are getting 14v at the alt and not at the batt try a jumper from the alt to the batt. use a volt meter to look at the battery . read it with eng off then start and see if the voltage goes up. if it does you are charging. put on the headlights and see if the volts drop a little. That style alt needs a exciter charge to get it working. Where are you getting that?
