My Expedition has a volt gauge in the dash. An altinator pretty much will not do anything if the voltage is too low. A generator will start to charge from almost zero volts. Take a very long time to charge but eventually will. Let us keep this simple. If everthing in you system is working correctly....an amp gauge will show you that work is being done. After you start your machine the amp gauge will show 5 or even 10 amps. of positive charge. The altinator or stator, or generator are working to top off the battery. Same if you start turning on lites, power clutches etc. The gauge shows a negative till the charge system can catch up. When you measure your battery you are saying yup the battery is good. When you measure and you see 14.2 volts you can say yup the whole charging system is ok. A little better than clear as mud.
