Charging system troubleshooting

With Key On, Eng Off the one FLD wire registered 11.37V. This could be one issue; expecting it to be closer to 12V. Reconnected it to the alternator, removed the other FLD wire and grounded the spade connector to the alternator. With engine running, charging voltage still 12.07V at alt Batt; ammeter still discharging.

Maybe I misunderstood. This is what I thought didn't work but should have had the same result (unless its a bad wire connection)
