Can a battery with to many cold cranking amps burn up an alternator in 2001 vw bug?

No, a battery with too many cold cranking amps (CCA) will not burn up an alternator in a 2001 VW Beetle. The CCA rating of a battery indicates its ability to deliver current at low temperatures, not the amount of current it can draw. The alternator is responsible for charging the battery and providing power to the vehicle's electrical system, and it is designed to handle the current requirements of the vehicle it is installed in. If the alternator is overloaded, it can fail, but this is not caused by the CCA rating of the battery.
