I don't know how much voltage needs to be coming through the blue wire, so I don't really have a baseline. Seems to me like it should be at least 12v.
When you turn the key and the Charging/Alternator light goes on it is less then the battery voltage.
As you noted the 2 red wires eventually end up being connected to the positive terminal. So you disconnect the Alternator Connector and use one of the red wires to see what the battery voltage is at the connector. Then you turn the key on and check the voltage at the smaller slot which is where the blue wire goes to and you will get less then the Battery Voltage (because the resistance of the light bulb reduces the voltage just a bit).
