Alternator Gone?

[john]

Once the car is started, isn't the battery out of the question? Isn't the alternator running the car regardless if the battery is opperating or not? I will check the belt for deflection but I am pretty sure it isn't slipping. I will also check my distribution block to see if the wires came loose but wouldn't it be all or nothing there (car would have power or wouldn't)? I don't really wanna check the battery because of the way I mounted it in the trunk. It is a PITA to get the box off. Thanks for the help.
