One important thing to check on a C900 is the ground wire from the alternator to the engine block. If the lugs on that are bad, then current can't make its way from the alternator to the battery.
One of the failure modes for the alternator is worn brushes on the voltage regulator assembly. It's held onto the back of the alternator (towards the front of the car) on the left side of the back of the alternator (as you're looking at the back of the unit in normal operating position) by 2 screws. Before you put the new alternator in, take off those 2 screws and pull the voltage regulator assembly and see how long the 2 carbon brushes are. They should each be at least 1/2-inch long or so and curved to match the sip rings.
Here's a link to a page that has some pictures. The voltage regulator is shon on the top picture. The cap of the regulator is a blackish circle, slightly to the left of where the cable goes into the alternator.
