Alternator Charging Help...

Following are the reading I got with my meter.

With the engine not running and all wire connected to the Alternator:
The large wire read 13.6 (Feed back from the battery I assume)
The two small wires with slide on ends read 0.0

With the engine "running" and all wire connected to the Alternator:
The large wire read 12.8
The two small wires with slide on ends read 13.8 & 14.0

With the engine "running" and the large wire disconnected from the Alternator:
The large wire "post" read 5.9
The two small wires with slide on ends read 13.8 & 14.0
