Or if you have a volt meter you can test it. With the engine running check the voltage output of the alternator with a volt meter (should be approx. 13.5-14.0 volts)? It should be nearly identical reading at the battery. If it is less than that there is a D shape hole on the back side of the alternator. Inside that hole is a metal tab. Using a small pocket screw driver ground that tab to the side of the alternator while monitoring the voltage. It should go up, may go over 14.0 volts, so don't leave it on it too long. The alternator may even moan while the current is flowing out. If it does work it look like the internal regulator at fault and will need to be change.
Let us know what you find.

With the voltmeter, I've got 12.3V at idling so way too low to my opinion and no change while rpm going up of course.
For the D shape, I'll have a look.
