If you have a voltmeter, measure the voltage across the battery, with the engine running.
It should measure around 13 -15 volt (alternator is ok) now turn the engine off it should measure 12volt. If you do not have a voltmeter ,let a friend watch your headlights at night with engine running,than turn engine off, your headlights should go dimmer with engine off.
