Disconnect the battery, disconnect the red wire on the alternator stud, disconnect the (2) wire connector on the alternator. Reconnect the battery, turn the ignition to the run position, check both red wires and the brown at the alternator and make sure there is voltage on all wires.
Per your description, I believe you will not have voltage on one or both of the large red wires.
Let me know.
