Dieselsnowmobile: I recommend that you stop reading that nonsense on wicked-pedia so you can learn some factual information.
1) there is Direct Current - a constant electrical flow in one direction only
2) there is Alternating Current - fluctuating flow swapping directions with the "cycles" (Hertz).
3) An Alternator produces only Alternating Current (like in your house!!).
4) By definition, an electrical generator can produce either an AC or DC. B-U-T, in automotive applications,the term Generator is usually found as meaning a DC producing device.
5) Auto batteries store direct current!! Early auto's used a DC generator with a voltage regulator to maintain the charge in a DC lead-acid storage battery. Modern auto's use an Alternator which has a diode to convert the electrical flow to Direct Current to recharge the lead-acid DC storage battery!!
Caution!! Using Internet souirces like wicked-pedia as definitive sources of information usually leads you into the"wild blue yonder".
