alternator smokes at startup, on 2007 Dodge Caravan

i was sitting in van with heat on and the alternator cooked in about 2 minutes, no warning lighs came on and it got so hot it melted the belt as well, so i replaced the belt and alt, and have the same problem,im thinking a wire shorting out, any suggestions?

Check for driven componets locking up other than the alternator, look at it while eng. is running with ac/ defoster on.
