Help! Lost tachometer, water t. gauge, alternator wont charg

[Saber]

Thanks Ivan. I haven't checked the back of the gauge cluster. Will do the next time I'm in the garage.

Let's say I wanted to check if the alternator is giving an electric charge, would you measure it with a volt meter and which terminals would you measure? (I have an idea, but I just want to be absolutely sure.)

EDIT: Of course I know that I can measure the battery while the car is running and should get around 14 volts if the alternator is working (which I don't). What I mean is, can I unplug the alternator from the wiring loom and simply measure the terminals on the alternator, to be able to rule everything else out?
