There is something that is being overlooked here. Start again and check ALL power and grounds, is the connection at the starter solid? Is the ground to the right motor mount bracket from the frame rail tight? Is there a voltage drop from the battery to the alternator? Is there battery voltage at the alternator with the key off? Power flows from the battery to the starter to the alternator. Battery voltage when running should be about 14 volts. The blue "field" wire should be checked for proper torque.
