You disconnected the field wires from the alternator. Disconnected the green and blue wires from the alt
Connected a test light between the blue wire's field connection and ground, and it lit with the key turn to run. To check for power on the blue wire with key on
Then connected a test light from the battery positive to each field terminal on the alternator. not sure what i was trying to prove with this(checking grounds) but found it interesting that both male connectors on the alternator fields signaled as ground. maybe means nothing.
