Is it discharging while you drive?? maybe the battery it up to snuff and every thing is just fine. If the battery is fully charged your not going to see a large deflection of the ammeter. How ever while your driving and you pull the lights heater and radio on and it shows a large discharge then you have a problem.
The ammeter is only showing you what the condition of the battery is in at any given moment.
