2001 v6 accord alternator problems?
 

my girl has a 2001 v6 accord and she has been having alternator problems. i have had to replace it 4 times in the last year and a half. im kinda getting tired of replacing it and buying her new ones. i thought i bought a defective refurb. alternator the first time at autozone so i went to honda and bought a brand new one. it still goes out, i have a new battery and i put new posts. ive taken it in twice now for new alternators and for troubleshooting and they cant figure it out. shes in puerto rico right now and she wants it fixed when she comes back. please help i dont want to hear her complain anymore!!!!!!!
