I think the information above should include some basic diagnostic guide.
I was made to change the alternator on my Honda crv 2007 model three (3) times but the battery light keeps on coming intermittently. -
Did you use a new factory alternator? if you did, then the next step is to check the wires from the alternator to the PCM
