If your ammeter does NOT drop down to a few amps after running a little bit you have a battery or wiring problem. If it were to stay that high with a good battery you would soon boil the water out of it. What the meter is reflecting it the amount of amps going to the battery to recharge it after starting the engine. The ignition system and lights are getting power from the alternator and so no power is going through the ammeter to those things unless the alternator output drops so low that it can not keep up. They will then draw power from the battery and show a discharge. Ammeters have been mostly replaces with voltmeters on equipment built in the last 30 years or so. A voltmeter will better show what the alternator is doing since if the voltage stays around 14.5 the alternator is producing enough amperage for the system. A drop in voltage means that the system is not able to meet all the demand that is being placed on it. If the alternator was able to produce only enough to maintain the voltage at 12.8 volts a ammeter would not show discharge since the voltage would still be above battery voltage, but the battery would end up going dead because there would not be enough voltage to recharge it after starting the engine. A voltmeter would show this low voltage problem.
