2006 honda odyssey ex v6...last week the battery light cane on. I replaced the battery but no change. Determined the alternator failed. After changing the alternator, the van runs fine. The first 2 days with the new alternator were fine. Third day the battery light started flashing randomly. Van still runs fine. Any suggestions on what might be wrong?

 

welcome to the forum. Alternator may have a defect, take it back and have them do a run check on it. Also do a load check on the battery.
