Check all connections on the battery and alternator-makes sure its wired correctly in accordance with the electrical wiring diagram.

Start the car -put a voltmeter on the battery what is the reading? Get back

There such thing as manufacture's defects-check your wiring and report back-regulator burning sounds like it not controlling the alternator
